Convert MCID to THETA

Altair Forum User

Hi,

Is there a way to quickly convert MCID assigned to a shell elements (e.g. CQUAD4) to THETA angle values?

Thanks

Hi 

 

When you assign a material orientation, in the element for example (using MCID or Theta) you are defining the material coordinate system of the element. I think there is no direct method to convert MCID to THETA angle value. It has to be input separately.

 

Thanks

A Tcl script can do that.

But why do you have to convert it?

Thanks for replays.

I need to convert it because the loads were extracted in element coordinate systems, so the theta angle in each element is 0.0 and load directions are not consistent.

I could re-create reports with loads extracted in a local coordinate system, but it would take some time to generate hundreds of reports, and besides current reports have been already used in other assessments so replacing them would further add work. Therefore, it seems to be quicker to transfer current loads using appropriate rotation angle.

 

I found out how to convert MCID to theta angle using competition FE software.

Hi MarekS

 

Check whether this TCL script can help you

Thanks a lot, it works!

There are small differences (~E-02) at few locations when comparing to what Patran produced, but I guess these are rounding errors.
