Different properties with different solver

[mohammad 1]

Hi,

I have model in Hyperwork and i got problem.

In Hyperwork I can get output by solver, i have tried to do this but there is somethings strange happen.

 

The grids parameter in optistruc fem and Nastran dat file are the same but when I apply the load to hyper-view, the values are change?!

I don't know why this happen.

Here the excel file and show this.

Any comment?

 

Best,

Mohammad

Hi Mohammad,

 

Are the loads and Bcs same in both Nastran and OptiStruct?

 

Can you check if there is any difference in magnitude and direction of the loads in both cases?

 

Small deviation may result in difference between the results.
