  1. Hi, I am new in Altaír Simlab. I am currently doing my final degree work and I’m using Altair SimLab to carry out a linear static study to obtain deformations in a planetary system. My problem comes when I want to refine the mesh. I have seen in different videos that it exists a method to create automatic refining. Could you help me by explaining how to apply this method? Manually refining usually causes me problems when I calculate again. I tried to create a response but when I'm going to check the convergence always appears this message. Thanls a loot, Sergi Valdezate
  2. Hi, I'm trying to refine a tetra mesh around a bolt hole after a topology optimization. OSSmooth only returns a mesh so I don't have any geometry, only tetra elements. I've tried using split elements but it doesn't seem to do anything as well as refine elements which apparently only works on shell elements. Any suggestions?
  3. I am trying to mesh a very complex set of 2D planes which intersect at varying orientations. THe first image shows an example of the type of geometry I am working with. I am able to mesh the geometry, however, the numerical simulation is not very stable due to some of the extreme distortion of elements at some of the intersections. I would like to know if there is a way in HM to refine these problem areas automatically. Is there a threshold value that I can adjust. I am new to this software and also to finite element meshing in general. I also attached a picture of some of the problem areas I am referring to.. you can see in the black circles that some of the elements are collapsed and therefore very small relative to the nearest neighbour.. I think this is the problem. How can I control this to get some sort of refining in these areas.
