Mathcad 14 - Ansys Workbench 11.0 SP1 This integration is a non-supported demo of the 2 products working together. The two products combine for a best of breed solution for customers. Mathcad runs inside of Ansys Workbench (AWB), providing natural math notation and optimization of parameters, with bi-directional communication with AWB’s Parameter Manager. Use Case Scenarios Mathcad can be used as a scratch pad calculation for Ansys customers in many ways. A typical use case is using Mathcad as a quick sanity check. Analysis results from Ansys can be sent to Mathcad to be compared with quicker, less computationally intense algorithms. Mathcad does not compete with Ansys in FEA, Mathcad does not do any meshing for example. But given simple volumetric information, Mathcad can conduct a myriad of stress/straining calculations, such as those from Roark’s Handbook for Stress & Strain. Again, giving the end user a quick sanity check of their results. Mathcad can also be used to check to see if the resulting analysis of Ansys is within safety constraints put forth by either the users’ best practices or maybe design constraints. Ad-hoc calculations such as computing the cost of the part all the way through to optimizing input parameters for rerunning the analysis are all available to the end user through Mathcad’s easy to use whiteboard interface. Installation of Mathcad-Ansys demo The demo starts with the connector rod CAD part. The part is provided as a ProE and as a SW part. The Ansys Input Geometry String filter is set to bring in only strings beginning with “DS”. Two files needs to be edited and updated to represent where you have installed the demo. MC.CONFIG is a file at the top level of the demo and simply contains the name of the Mathcad worksheet you wish to load. Ie. C:\jsheehan\solutions\Ansys\ansys_tierod.xmcd MATHCAD.REG is a file in the Application Directory. The InstallDIR and LibPath variables need to be updated. Please make note of the double backslashes. Here is what mine looks like : REGEDIT4 [HKEY_CURRENT_USER\SOFTWARE\ANSYS, Inc.\v110\APFramework\Addins\Mathcad] "BaseWinId"=dword:4a310b47 "InstallDir"="C:\\jsheehan\\solutions\\Ansys\\phase2\\Mathcad\\" "LibPath"="C:\\jsheehan\\solutions\\Ansys\\phase2\\Mathcad\\MathcadU.dl l" "Location"="SDKDLL.AppService.110" "Type"="progid" "UsesSDK"="1" After updating this script it needs to be run by double clicking on it. When the Mathcad Applet is selected from the Project Page of AWB 11, it looks in the registry for information about the DLL (Install Dir and LibPath). It then reads the MC.CONFIG file and locates the Mathcad worksheet you have specified. The Mathcad worksheet needs to be pre-treated. We edit the properties of regions we want to show up in the drop down lists for transfer between the 2 products. Mathcad worksheets can have thousands of regions and we do not want a drop down list to have thousands of entries. So we add a TAG to any region we want to use in the integration, Actually either one of two tags : Ansys2MC or MC2Ansys. Before running the integration demo, pre-treat your worksheet by right mouse clicking on any math region you want to be used in the integration and add one of the TAGs depending on which direction you want the number to travel.
