On the MSC website there is a Patran and a Nastran forum. but I found here in the dedicated forum nice threads and lots of people posting. So for the same reason there is a Patran forum that is the "OLD" MSC pre/post I was thinking a Apex forum would be interesting as is the "NEW" MSC pre/post...

I read the Nexus Forum, not often really, but seems not much frequented. Cheers Stefano

Hello Everybody, I'm a user of MSC.Software Apex and I would be very happy to find some other user and share doubts, bugs. I see that there isn't a dedicated forum and i was wondering if the software isn't much used. I believe it is a really interesting software with lots of pro, and some cons...

You can export the sketch in iges as curves. just check the settings for iges export in solidowrks, when the save as window open. then you can import the curve in patran by reading the iges file. Cheers

You can do an isomesh on a surface that has four edges, not on trimmed surfaces. in your case you can do isomesh on the cylindrical part but not on the two end cap.

Use a non uniform scale, and give the correct parameter for the length (X) and the radius (Y and Z) this shall modify your cylinder as desidered. Rgds

Plane with normal Y: Y=0 RX=0 RZ=0 Plane with normal X: X=0 RY=0 RZ=0 apply half the load you shall also constrain a grid point in Z to solve.

If you want to recover the stress from the surface of the cylinder, you can mesh the surface with very very thin shell with same elastic modulus of cylinder (in a separate group) (utility skin solid elements) and merge the grid points. then you can plot the stress on the shell. This will not...

I've tried to import your Iges file, and seems that everything is correct. Patran import 5 surfaces because there are 5 surface in the file. It is a box without a face. I've also meshed, and everything was correct, then I make an equivalence on grid points and the mesh was perfect. I never...

I think you can use a Cbush with correct stiffness and then apply to the node a preload with the correct torque due to 60 deg of deflection. so your model will see the load applied plus the load due to the angular deflection of the spring. starting from the "0" configuration you will only see...

Hi, I wrote the original post, and still here, using nastran, so I thank you for this update that could be useful for me. thanks a lot. Stefano

Why you want to use contact? if the model is as simple as the picture, you can simply model the two different materials with sharing grid points and you do not need any contact .

- 1 Usually you should apply equilibrated loads the ship. then you can use an inertia relief system to analyze your ship. Another system is to use the 3-2-1 system: http://www.roshaz.com/images/FEA_best_and_worst_practice.pdf you shall be very sure that your loads are equilibrated. -2If the...

Dear Jeff, thanks for the two links it is exactly the confirmation I was looking for. regards Onda

That is an option, but I just would like to know if there is any change in policy by Solid Works.
