  Hi, i have question regarding the error below:
  
  Element 302090 has excessive distortion.
  
  I located the element with distortion and the region has really thin structure (attached photo) that might be the reason causing the error.
  
  I tried to increase the mesh density to solve but the error remains. Is there any other suggestion to solve this problem if i am not being able to modify the geometry structure?
  
  If i run the simulation with extra fine mesh (which takes mush longer time), will the error goes away?
  
  Thanks.

  Serene, What version are you using? There is a limit to the no. of elements you can define in an Academic license.
  
  Also, what materials are you using and how are you loading this?
  
  This seems like a good candidate for NLAD but you have to be careful with how you use it (see here). See here and the manual (1 & 2). Here is another good article by one of our Channel Partners.
