  1. Hi, I have run a succesful setup with LS-Dyna and extracted the responses correctly, However when I run a DOE it succesfully evaluates however the runs of the DOE are skipped, it goes through them quikcly and I get this warning: 85 Warning: Skipping evaluation of model ( Parameterized_k ( Parameterized_k ) ). No Responses or retained Data Sources depend on this model. I am not sure why it does this as I am sure my response is referencing the correct file. s\HyperStudy\Test\approaches\doe_1-def\run__00001\Parameterized_k\matsum The doe file has all the run000 folders but they are all empty. Any help would be appreciated. Thanks,
  2. Sure - here they are. Many thanks in advance!

  3. IMPORTANT UPDATE: PROBLEM SOLVED The issue was that i had applied a full constraint (SPC) to a face on a solid that i had applied the all the loads and thus loadsteps onto - and made non-designable. i.e. the load fluxes did not propagate to the designable section - because i applied full constraints (SPC) to a face on the non-designable load-bearing solid section. Many thanks anyway! Fady

  5. Sure - when i run the optimisation, several files are saved. I believe they are all attached. Thanks!

  6. I should also add that i have made sure all my element properties are PSOLID. Thanks again. Fady
  7. Thanks!! This helps. now moving on to another problem. I get this. Messages for the job: *** ERROR # 2148 *** Invalid design problem. All the sensitivities of response 2 (objective) are zero. my response 2 (objective) is weighted compliance. I have 3 loads in 3 load steps that i assign to the weighted compliance. I click all and press create when doing so, but when i click on the yellow 'loadsteps' button again they all seem to be unticked... i am worried this may be the problem. Is there a way to check they are correctly assigned? If not, what may be the problem? When i run the check i get no errors. Many thanks! Fady.
  8. Any ideas why this is happening? I have the student version, but running a check gives no specific errors. This error arises when i attempt to run the full optimization.
  9. Is there no trick for meshing that can stop this from happening? This isnt specific for this geometry.. i get the same error i explained earlier alot for different geometries too.
  10. I made sure i only have solid elements. Now it gives me that elements have negative jacobian... is there any way to bypass the quality check? If not can you tell me tips on making sure the automesher makes all elements that pass quality check? it gives me no errors when i assign the properties and when i make the mesh... only when i move to the final optimisation for results. It is very frustrating.
  11. Hello guys, i have been trying to mesh several objects for the past few days. Everytime, it all goes correctly, even the meshing, loads, responses, and when i assign the properties it says "elements assigned". Now when i run the topology, it says job terminated at "Element Quality Check - element xxxx invalid element type". It does this almost everytime - no matter the component. I try remeshing, and activated the "REMESH" from 'opticontrol', i auto clean the geometry before meshing - same outcome. When i try to clean mesh elements it says "unable to create hmshell. Is there anyway i can bypass the element QI check? I always use Volume Tetramesh - PSOLID i can't fix all the broken elements manually. Please advise as this has been really delaying. Note: i have student edition so i cannot have more than 10,000 elements.
