    Changing the slope of spring in ANSYS Workbench

    Hi David, This should be fairly easy to do. To check reaction force: Right Click on 'Solution' > Insert > Probe > Spring You can then select which spring you want to look at the reaction forces (including the weak spring reaction force if you don't have those turned off). To change the...

    Best way to connect volumes? (or: how to convert 4 to 10 node tets?)

    Don't confuse nodes with keypoints. If you are reading in your point cloud file as nodes, then there are no keypoints defined. The first argument in the nummrg command defines what you're merging. I would suggest using the nummrg,all to start with (make sure you save before you issue that)...

    Convergence issues

    You can't glue in Simulation, because there *is* no geometry. All that gets passed to the solver is nodes and elements. If you look at your output file (or use Tools > Write ANSYS Input File), you will see that your named selections get passed as either nodal or element components. If you...

    Best way to connect volumes? (or: how to convert 4 to 10 node tets?)

    Oh yeah, one more comment. Try using the nummrg rather than a gluing operation. Just be careful you don't wind up merging stuff you didn't intend. Sorry for the double post, Doug

    Best way to connect volumes? (or: how to convert 4 to 10 node tets?)

    A couple of comments: 1 - Is it necessary to have all the interior points? Or could you just take the outer data points from your scan, form areas from them, and a solid from that? Then you could just mesh the internal volume 2 - Look up the help on the emid command, which will allow you to...

    moving mass

    D'oh, sorry for the typo. Obviously my last sentence should be "...time/position and go from there." Coffee hasn't kicked in yet.

    moving mass

    If it were me, I would make sure that my beam had multiple divisions in it. At each node, I would place a mass21 element. As I walked through each substep, I would use the ekill/ealive to remove/add masses to the current load step. Now, depending on what you're doing, you may need to divide...

    How to do a volumne sweep of element type solsh190

    Make sure that when you sweep with the solsh190s, the element is oriented correctly so the shell thickness is defined properly. If you look up help,190 it will show you the node order that defines the thickness direction. Here's a quick example if you still need one: finish /clear /prep7...

    Transient convergence issue

    Look up the help for the nldiag command. I believe what you want is: nldiag,nrre,X Where X is the number of Newton Raphson residuals you wish to store. Hope this helps, Doug

    Merge nodes of coplanar faces in WB

    If you have Design Modeler, it's easy, just use the 'Form New Part' capability, which is the same as 'vglue' in the ANSYS Classic environment. You could try inserting a command snippet to merge the nodes, but I wouldn't recommend it. The reason is because when WB tries to read in the results...

    ENTH?

    ENTH is the enthalpy. Look up the help on the 'mp' command. Hope this helps, Doug

    Using cohesive elements

    Try this out: http://www.padtinc.com/epubs/focus/2007/0056_0420/TheFocus_56.pdf#Page=3 There is a link for an input script. Hope this helps, Doug

    Pro/E import configuration

    If you look in the release notes, you'll see that they removed this utility from the ANS_ADMIN utility. The settings are now defined in the config.anscon file. Hope this helps, Doug
