  1. akshay eranholi 0 Started conversation: 20 hours ago · Report Sir, Can you please provide me with the definitions of skew, warpage,aspect ratio,jacobian, elements and nodes I found this by google, perhaps your concern: http://www.altairuniversity.com/wp-content/uploads/2012/04/Student_Guide_211-233.pdf
  2. Hello Everybody, I am trying to bring a good quality hexa mesh. The mesh I am getting is good in almost all the quality criteria except 'aspect ratio'. I am getting the aspect ratio values in range 3 to 5. I have read that the acceptable aspect ratio is below 5, so my mesh should work. But what I am expecting is to get a good quality mesh in the area since it may be the region of high stress. My question is how good my mesh is if it is to rate between 1 to 10? (I am getting a very good mesh for rest of the quality criteria) And to what extent my results may get affected if I fail to bring a proper mesh in the region? The attached illustrative image may be referred. The 3D mesh will be connected to 2D mesh and the the analysis is explicit (Radioss). Please advise.
  3. I have used OSSmooth command for my found topology but it seems impossible to re-run the analysis as it contains so many meshing errors. My element quality check identifies 4795 free edges. I tried re-meshing the whole volume and re-assign my design/non-design space but it didn't help. Is there any solution for this matter? Optimization.hm
  4. Hi I am working on crash analysis (having 37 components) and in my model for a minimum element size of 0.25 inches, I have about 28000 elements failing. is there any way to clean up these elements other than the conventional way of editing each one separately. Thanks, Datta
  5. If i start a new modelling in Hypermesh by importing the IGES model and mesh it, after that if i check the element quality (say for skew), all elements are passing for this skew criteria and max skew observed was 40.00. After that if i export the same model as bdf/dat and then re-import that bdf/dat file into Hypermesh, after that if i check the element quality it is varying, Max skew is coming around 40.65. I'm facing this issue for TET collapse criteria also. It happened with me for lot of models not for only one. I'm currently using Hypermesh 2019 version in Windows 10 machine. Anyone else faced this issue before?
