You may have to reset your limits to view all of your geometry. It's been awhile since I've used autocad, but I believe "zoom extents" effectively resizes the limits. Or you can issue the limits command to resize them. The limits command does not effect how big the geometry can get it just...

You are correct, you can't insert a command on a slide curve joint, you will need to control the motion with another joint in your mechanism. If you are using a point curve joint, you will be able to control it by the length along the curve. However you need to restrain the rotation of the...

Thanks Drej, That makes sense, most of the problems we analyze are bending dominated (stamped brackets and such) vitually none of the loading is in plane. I guess thats why "standard practice" in our company was to use three elements through the thickness. We also do non-linear analysis to...

Thanks for your response, could you clarify what exactly you mean by "in plane response". I had run a test case in which I compared the results of using one element vs three elements through the thickness of a simple rectangular beam. I then compared these results with hand calculations, the...

If the channel follows a curve you can use the point curve joint, or the slide curve joint.

Is there a method for pre-determining an appropriate mesh density? I know one method is to keep refining the mesh size until you get a converged solution. This is fine for linear analysis but I don't want do use the same methodology for non-linear analysis as there is considerable wait time...

To answer my own questions: -The Solsh190 element meshes the same way as you would mesh a solid, which also makes contact easier to set up. -No, you still need to use at least three elements through the thickness of the shell to get accurate results. -The benefit over solid elements is that the...

You could also use the KDIST or the NDIST commands. These are available in the preprocessor menu. modeling/check geom/KP distances or ND distances.

Catia V5 has a V4 to V5 migration tool (translator), which has a few options. In order to use the "history tree" you can import using the "as specified" option. You can then edit/make changes to the model. However, sometimes some operations end up with errors which you have to correct in...

It would depend on how accurate the position, size, and shape of the holes have to be.

If you used the "defeature" option when you imported the iges file then you won't be able to modify the geometry. If you didn't defeature, then follow the procedure given by ghx. bhava9, I think you might need LS-DYNA to do an impact analysis.

We use a software called Myriad Engineering Viewer http://www.myriadviewer.com/

Thanks Catiajim! I agree that the best way is to use the Assembly Design workbench to position and orient the parts. The only problem is when customers demand to have the parts located in "body co-ordinates".

You can use the translation and the rotation tools to locate the part in the "proper" position. However, it is quite time consuming to get the proper orientation of the part as you have to specify an axis of rotation and a rotation angle. I haven't found anything to orient a part along a...

Does anyone know how to properly use this element? According the the literature, it is supposed to help with modelling contact between shells and solids. Can you use this element replace the shell elements in a model so that you will no longer have a gap between adjoining parts, thus making the...
