Ignore distortion elements

[akaszynski]

This PR ignores errors that do not cause solves to fail, like distortion errors. Also returns a better error in Linux when finding the MAPDL path. See #352.

 *** ERROR ***
 Element XXXXX (type = 1, PLANE182) (and maybe other elements) has       '
 become highly distorted.  Excessive distortion of elements is usually   
 a symptom indicating the need for corrective action elsewhere.  Try     
 incrementing the load more slowly (increase the number of substeps or   
 decrease the time step size).  You may need to improve your mesh to     
 obtain elements with better aspect ratios.  Also consider the behavior  
 of materials, contact pairs, and/or constraint equations.  Please rule  
 out other root causes of this failure before attempting rezoning or     
 nonlinear adaptive solutions.  If this message appears in the first     
 iteration of first substep, be sure to perform element shape checking.
