  1. I am not sure what sT Inspire is? Is it a software? I googled it but I am not getting any software. The use is for a CFD simulation
  2. I am using the HyperWorks 13.0 Student edition and I created a mesh on a geometry. I would like to export the mesh as a STL file. Under Export Solver Deck I only get options for OptiStruct, RADIOSS and CFD. There is no option for STL. How can I export the mesh as a STL? Or is it not possible with the Student Edition?
  3. I have HyperMesh 11.0 installed on Windows XP. I don't see any of the folders that you specify. When you run the above script and perform the boolean difference does it give you a dimple?
  4. I want to perform a difference operation A-B, not an union. In this case A is the big sphere and B is the small sphere. The small sphere definitely penetrates into the large sphere so the difference operation should work and produce a dimple like shown in the picture (the small sphere in the picture was mirror in X, instead of -0.566639982 I changed it to 0.566639982). Why does the boolean operation fail though?
  5. I am trying to perform a simple boolean operation, subtracting a small sphere (radius 0.1131) from a large sphere (radius 0.5). I am using a script to create the two spheres: *settopologydisplaytype(1) *createmark(materials,1) *clearmark(materials,1) *collectorcreateonly(components,"point","",3) *createmark(components,1) *clearmark(components,1) *createmark(components,1) "point" *materialupdate(components,1,"") *createmark(components,1) *clearmark(components,1) *createmark(components,1) "point" *clearmark(components,1) *createmark(properties,1) *clearmark(properties,1) *createmark(materials,1) *clearmark(materials,1) *createmark(elements,1) *clearmark(elements,1) *createnode(0.0,0.0,0.0,0,0,0) *collectorcreateonly(components,"ball","",3) *createmark(components,1) *clearmark(components,1) *createmark(components,1) "ball" *materialupdate(components,1,"") *createmark(components,1) *clearmark(components,1) *createmark(components,1) "ball" *clearmark(components,1) *createmark(properties,1) *clearmark(properties,1) *createmark(materials,1) *clearmark(materials,1) *createmark(elements,1) *clearmark(elements,1) *solidspherefull(0.0,0.0,0.0,0.5) *collectorcreateonly(components,"sphere_140","",3) *createmark(components,1) *clearmark(components,1) *createmark(components,1) "sphere_140" *materialupdate(components,1,"") *createmark(components,1) *clearmark(components,1) *createmark(components,1) "sphere_140" *clearmark(components,1) *createmark(properties,1) *clearmark(properties,1) *createmark(materials,1) *clearmark(materials,1) *createmark(elements,1) *clearmark(elements,1) *solidspherefull(0,0,0,0.1131) *createmark(components,1) "sphere_140" *createvector(1,1.0000,0.0000,0.0000) *translatemark(components,1,1,-0.566639982) *createmark(components,1) "sphere_140" *createvector(1,0.0000,1.0000,0.0000) *translatemark(components,1,1,-0.179599557) *createmark(components,1) "sphere_140" *createvector(1,0.0000,0.0000,1.0000) *translatemark(components,1,1,0.109171287) *retainmarkselections(1) *currentcollector(components,"ball") *retainmarkselections(0) The two spheres as shown in the image attached intersect each other. However when I try to perform a boolean difference (removing the small sphere from the large one) the operation ends up just deleting the small sphere without subtracting it from the large sphere. Any idea what is wrong?
