HyperWorks Desktop 2017.2.2 Release Notes Introduction HyperWorks Desktop 2017.2.2 hotfix contains enhancements and bug fixes for HyperMesh, HyperView, HyperCrash, HyperForm, MotionView, Motion Auto, HyperStudy, NVH Director and HyperWorks Verification and Validation Harness (HVVH). The details are documented below. Note: HyperWorks Desktop2017.2.2_hotfix is a cumulative release. It should be installed on top of HyperWorks 2017.2 release. HyperMesh New Features and Enhancements Engineering Solutions: Aerospace Profile • Create and Review Zero Length Elements This tool creates zero length elements (CELAS*, CGAP, CMASS* and CBUSH) between disconnected nodes within a given tolerance or between selected congruent nodes by detaching them. With this tool, you can: • Identify coincident nodes • Create 0D elements between disconnected nodes within tolerance • Create 0D elements between connected nodes by detaching the nodes picked • Import, Export of Data using the Entity Editor This function can import, append or export CSV files from EE table data for the following cards – PCOMP, PCOMPG, TABLEM/S/D HyperWorks Desktop 2017.2.2 Release Notes 1 Proprietary Information of Altair Engineering This helps you update table entries in EE without manual typing. • Ability to Transform Systems using the Transformation Tool The Transformation tool can be used to transform system in few different ways. • When components/ elements are transformed, systems are also transformed if the system was created using nodes (origin node, x direction node, y direction node) from those elements/components. If some of the anchor nodes are not associated with any of the transformed element, the association is broken and a new system is created while transforming using axis definition instead of node definitions. HyperWorks Desktop 2017.2.2 Release Notes 2 Proprietary Information of Altair Engineering • If the system is not associated with elemental nodes which are being transformed, then you can only select “system” and it will transform as an axis system. • Creating Linear Gap Elements Automatically This tool can be accessed via Aerospace > Connections > Linear Gaps. This will create old Nastran linear gaps that contains MPC, SPC, SPOINTS and SUPPORT and allow the user to set up the corrispondant parameters (CDITER, CDCPH and CDPRT) to control this type of analysis. Example: The following cards will be created. • SPOINT 55 155 ( two spoints 55, 155) • SUPORT 55 0 ( support at one spoint) • SPC 101106 155 0 .05 ( spc at the other spoint with initial gap of 0.05, with DOF=0) HyperWorks Desktop 2017.2.2 Release Notes 3 Proprietary Information of Altair Engineering • $ SID G1 C1 A1 G2 C2 A2 ( MPC for linear gap. In DOF =2. for Nastarn) MPC 101106 3 2 1.0 2 2 -1.0 $ G3 C3 A3 G4 C4 A4 55 0 1.0 155 0 -1.0 This tool can also convert other types of 1D connector elements (CGAP, CBUSH, CELAS) to linear gap (MPC /SUPORT, SPC, SPOINT). • Visualize CBAR Beams on the Centroid instead of the Shear Center Even for Non-bi Symmetric Sections In previous releases, HyperMesh exposed a global option called “1D at Centroid” (available in the Options panel; keyboard shortcut “o”). This option drives the display of beam section 3D representation either at its Centroid (“on”) or its Shear Center (“off”). In the image below, you can see 3 straight lines meshed with 4 CBAR and 4 CBEAM each. A T2, L, and Hat section was assigned, respectively. “1D at Centroid” is “on” so each GRID matches with a section’s Centroid. HyperWorks Desktop 2017.2.2 Release Notes 4 Proprietary Information of Altair Engineering If “1D at Centroid” is switched “off”, HyperMesh represent the 3D detailed view with GRID at section’s shear center. However, when using a CBAR element, its elastic axis, gravity axis, and shear center all coincide for the solver. In the example, sections for which shear center is offset from centroid were used. In order to reflect what the solver actually considers, HyperMesh now displays the section based on element formulation (always at centroid for CBAR) • Import and Check Ground Check Forces This tool, available in Nastran profile only, can be accessed via Aerospace > Results > GroundCheck Forces HyperWorks Desktop 2017.2.2 Release Notes 5 Proprietary Information of Altair Engineering Select an f06 file where the GroundCheck forces have been asked as well as output (e.g. GROUNDCHECK(SET=(G,N), DATAREC=YES)=YES) Once the file has been selected, the tool parses it and recognizes for which set the output has been required. You can select these sets and the relevant results will be available in the “Select Result Cases” box. You can select one of the results and then one result type to contour (a vector visualization is as well available for both translational and rotational DOFs). In the example below, Mode G-Set, direction 6 – Translation Magnitude has been selected. Matrix Browser technology is used in the background to apply the contour. You can create a HWASCII file and use it in a HyperView session. HyperWorks Desktop 2017.2.2 Release Notes 6 Proprietary Information of Altair Engineering In this case each set will be treated as load Case, direction as simulation (mode) and results nested in the vector root. The checkbox “Use Failed nodes only” implies if results will be created for failed nodes only or for all database nodes in the database. • Fringe Post-processing Using Different Volume Averaging Methods This tool can be accessed via Aerospace > Results > Averaged Post Processing; The tool enables you to evaluate, for the selected elements, the averaged value of the selected result type (component, layer and system). Three different options are available: • None: no ponderation value will be used • Volume: the exact volume of the element will be taken as ponderation value • Area: the pondered value will be the length for 1D elements, the area for 2D elements and the volume for 3D elements You can select more than one subcase. HyperWorks Desktop 2017.2.2 Release Notes 7 Proprietary Information of Altair Engineering Two options are available for the contour selection: • Set Up on Active Window: Add, Remove or Duplicate Rows in the available UI. By Adding a row you can set up the whole configuration of Data Type, Component, etc. In addition to the pondering value, you can set up a min/max filtered value which will tell the tool the range of result values that will be extracted. This result configuration can be saved (and afterwards loaded) via CSV file data format exchange using Save and Load Config. buttons respectively. HyperWorks Desktop 2017.2.2 Release Notes 8 Proprietary Information of Altair Engineering • Select from Session: You can select the available contoured results from the HyperView client in the session (Type/Component/Layer/System entries are therefore frozen). Set up the pondering option and as well the min/max value as contour filter. As outcome, a new UI is displayed where all selected combinations can be accessed. Results can be saved in a dedicated folder. In addition, use the option “use Matrix Browser” to generate a table for each combination which can be processed using the Matrix Tool. HyperWorks Desktop 2017.2.2 Release Notes 9 Proprietary Information of Altair Engineering • Enabling Ability to Control Nodal Coordinate Precision (rounding off) This tool can be accessed via Aerospace > Nodes > Precision Control. This tool will round off the node coordinates (multiple nodes) to the desired precision and update the HM data base. Before update After update • CBUSH Node to Node Connector in Aerospace Fastener Tool This tool will create Node to Node CBUSH elements at the connector locations provided either point/node or line locations. It is mandatory that users to make sure the nodes are opposite each other when two plates are connected (congruent meshes). If the meshes are not congruent, it is advisable to use RBE3-CBUSH-RBE3 or CFAST connector type from the same dialog. Note: It is required to provide Rivet diameter manually for this tool to work, or have axillary lines to represent the diameter. • Manually Synchronizing System between HyperMesh and HyperView This tool can be accessed via Aerospace > Systems > Sync HM-HV; This enables you to have the same system defined in both HyperMesh and HyperView clients. If a system is defined in HyperView session not present in HyperMesh, the missing system will be created in the session. This tool currently supports Rectangular and Cylindrical systems but not Spherical ones. • Aircraft Transformation Tool This tool can be accessed via Aerospace > Assembly > Aircraft Transformation Tool. HyperWorks Desktop 2017.2.2 Release Notes 10 Proprietary Information of Altair Engineering This tool allows to apply a full transformation (translation+rotation) to the following entities: • Elements • Nodes • Components • Systems Four different methods are available to input the transformation matrix: • By Config File: in this case a CSV structured needs to be imported, as in the example below Once the file has been loaded, you can set up Reference and Destination point. HyperWorks Desktop 2017.2.2 Release Notes 11 Proprietary Information of Altair Engineering • By Direct Input: Directly input the transformation matrix in the given fields • By System: Select reference and destination system from those available in the HM database. The found transformation matrix will be stored as CSV file. • By three nodes: This function re-applies the Position tool where three nodes as reference and three nodes as destination are used for the transformation • Also in this case, you can save the transformation matrix as a CSV file. In addition, when the Component is selected, the tool allows you to transform the found associated systems. • Conversion of Elemental Pressure to Nodal forces on the Same Model This tool converts pressure load to be applied on shell elements to equivalent forces on the corner nodes of the selected shell elements.
