Hyperwork Optistruct model missing some element stress results

Hi,

 

I ran a 2D shell model with MAT 1 steel proper ties and it worked fine. I then morphed some surfaces and not the stress results in some surface are missing. The deflection plot shows results on all elements, but some stresses are missing. The surfaces are linked to the elements and there are no duplicate elements. 

All output parameters are set correctly as well and when viewed in hypermesh the results are present. 

All components are assigned the correct property, so is there another way to check what elements are selected to produce results? 

I would also like to understand whether this is a graphics issue in the software or something is not set correctly in the model.

    really strange.

    Don't you have a SET of elements where you request stress values? That might be changed somehow?

     

    If you think it might be graphic only, can you check your graphic card driver version if it is up-to-date?

    This model worked in the previous iteration. I out results for the whole model. I altered the mesh and surfaces with morphing, but I already deleted the mesh and remeshed all the affected areas. Somehow this persists. Is there a way to rewrite the output card the clear out any unwanted script? Or reassociate the mesh and surfaces? When I query the elements it states that the results are missing, but only for stress not displacement. It's works in hyperview, but I am concerned something is wrong in the model/mesh or both.

    when you load your model in HV, do you usually load your .fem file and .h3d? or just the h3d?

    Is there any chance that you're loading and old .fem with a new h3d with different ids?

    I load the latest h3d file in HV. I tried opening the model after a fresh restart and importing the results file, but it still happens. I saved it under a new name, deleted the affected areas and remeshed it, but the blank areas still appear.

    any chance of sharing the model?

    Is there a way to share the model that is not open source?
