Hi everyone,

I have looked everywhere and read heaps of docs but I could not find an answer to this. For someone it is probably a very simple fix. Your help will be greatly appreciated!

So, I used design modeler to draw a system of beam and shell elements as shown (in the attachments). It's a net system. The frame and the outer poles are all modeled as beams (different cross-sections) whereas the ball and the net itself are surfaces.

I am using explicit dynamics.

Now, to the problem. As you can see in the results (Von-mises equivalent stress), only the stress results of the surfaces are shown. But what i really want is the stress (bending) results in the pole and the frame. (Beam stress tool is not even available to choose so I could not try other beam specific solutions)

Help please! cheers!!

This part of the User Guide (help/wb_sim/ds_probes_structural.html) says stress on bodies using probes in explicit dynamics. Not been able to get it to work though and a test gives the warning "No stress/strain results are found on beams. Please set the Beam Section Results to Yes" but haven't found that option.

After a bit more searching in Solution / Post Processing you can set Beam Section Results to Yes and this activates the stress / strain contours and probes.

Thanks Siw!

When you click "Solution" under "Explicit Dynamics" tree, there is "Calculate Beam Section Results". However, when i run the solution with this option on, I get a warning message "Beam Stress/Strain results are reported in solution coordinate". So it seems the solution is there somewhere. But I still can not retrieve the results. The fault is probably with my approach. But defining path as well as using probe were not successful. (I get 0 stress results with the probe)

The option I said above is a mistake, so leave it off you just need to make User Defined Results from the Worksheet with STRAIN_1 for beam strain and BEAM_MISES_STR for beam stress.

You are a champion!
CHEERS!!! it worked!
So I am guessing BEAM_MISES_STR is an equivalent of Von-mises?
