RPT file and displacement plot have different values

Hi all,

I am running a simulation of a part in CREO Simulate and the RPT output from the simulation does not match what the displacement plot shows when viewed in the simulation results. I have checked the units and the RPT file should be set to output inches (the part units setup is set to CREO default), and I don't think the RPT file can be referencing another run because I watched it output these numbers as it completed the most recent run. The simulation window is set to display the displacement in inches as well. The legend is set to view max and the info > model max tool displays the same displacement. I have never noticed this happen before, and am at a loss for what could be wrong and for what output to believe. Has anyone else run into this issue?

Thanks in advance,

Matt P.

Matt,

Try to increase the plotting grid value to the highest value possible and run the analysis again.

Thanks Ruben, but this didn't seem to work, it still gives the same result in the RPT and in the display.

Re: RPT file and displacement plot have different values

If I set up a default view from simulate, no scale is shown. If I use one of my templates, I see a scale of 2.26E1; both result screens show the same maximum displacement of 0.053" where my report shows 0.112".

Unfortunately, I can't share the model.

Re: RPT file and displacement plot have different values

Mat,

What version & cut of the s/w are you using?

Re: RPT file and displacement plot have different values

Release 2.0 of Creo M160

Matt,

Do you have multiple load sets in your model? If yes then are you running for combined load sets?

This might be one of the reason for the difference in the results. try to run individual load and check.

Re: RPT file and displacement plot have different values

In the original model, there wee multiple load sets. Each run was only using one of the loadsets though. This new model I made only has one load set and I see the same issue still.

Re: RPT file and displacement plot have different values

So, I found the cause of this issue, but have no idea why it happens.

I was attaching an external load to my model using rigid links; there is an external point mass and I rigidly linked it to some mounting holes on the model.

When I remove the links, the RPT file and results window agree on the result perfectly.

That seems a bit bizarre to me but it resolved the discrepancy. If anyone has any thoughts on why this happened please feel free to share...
