    License loss after solving

    No, the ANSYS Academic Research license is an integrated or single-task license, which means that if you use it for a batch run, it is used throughout the analysis run. If this is an intermittent problem, perhaps it could be due to network instability? The ANSYS client checks in with the...

    How to parameterize a cad model in ANSYS?

    If you are planning to perform your analysis using the Workbench Mechanical environment, then you can consider using the ANSYS SpaceClaim Direct Modeler product. It can parameterise the dimensions of a model.

    comparison multiphisics ver 10 vs ver12

    That's true, and ANSYS 12.1 is a more robust release of 12, especially the Workbench Meshing and additional beta features in Workbench Mechanical.

    Ansyslmd.exe problem

    Try restarting the machine. I think the ansyslmd chews up CPU cycles after a return from hibernation or standby.

    Contact after load increasing

    It would probably be easier for your model to converge if you impose a displacement load. After the model has converged, you can refer to the contact pressure results to check the load needed to cause the contact to close. Also, you may consider modeling your parts to just about touching, so...

    Transient analysis in ANSYS Classic

    It looks like your solution controls and the solve command are in the preprocessor level (/PREP7). Try moving it to the solution level ie add /SOLU before your transient analysis solution settings.

    Transient Thermal-stress analysis

    Yes, if you use the 2nd method, you will have to solve the thermal-stress portion sequentially and for all the substeps that you want to extract a plot of the displacement. This is best done with an APDL script and a *DO loop.

    Transient Thermal-stress analysis

    I can think of 2 methods: 1. use direct coupled field elements and you can post-process the animation as required 2. for each time step that you have done a (sequential) thermal-stress analysis run, export out a plot in the same orientation and scale. Then, use a graphics program to create an...

    SF command (Electro-Thermal Analysis)

    You don't need to calculate what's the film coefficient value, since it's interpolated from the temperature dependent HF table that's defined.

    Define thermal Resistance between surface

    You can consider using the bonded contact option, and specifying the thermal contact conductance (TCC) between the surfaces.

    Import geometry from ANSYS Workbench to ANSYS Classic

    Why not just complete the analysis in Workbench, since it's so much easier to perform the modal analysis in it? If you want to take the FE model (only) into the classic environment, you can either write out a DB file after solve (check the Details options in the Analysis Settings branch), or...

    Import NASYS Classic geometry to Workbench

    You may transfer the solid model from ANSYS classic GUI to Workbench via the IGES neutral file. Go to Utility Menu > File > Export command while in the Preprocessor level to export a jobname.igs file.

    exporting model from WB to ansys classic

    Note that the Workbench Simulation's DSDB file is not the same as the classic GUI's DB file. Also note that only the FE model (nodes and elements) is transfered to the classic GUI. The solid model (volumes, areas, lines and keypoints) do not get transferred from Workbench to classic GUI.

    Connect individual bodies in ANSYS Workbench

    If you are working in the ANSYS Workbench environment, you will need to create multi-body parts (similar to a Boolean glue or overlap operation in the classic GUI). However, this operation can only be done with the help of the DesignModeler module in Workbench.
