Hello,<\/p>\n

<\/p>\n

Could someone with experience in dealing with modeling nearly incompressible materials explain the pros\/cons and differences in utilizing the Uniform Reduced Integration with hourglass control (keyopt,matid,2,1) versus Enhanced Strain Formulation (keyopt, matid, 2,2) for SOLID185 elements? Also, for URI, the notes from sharcnet indicate to measure the ratio of the artificial energy to total energy and ensuring this is less than 5%. Can someone please explain, in the ANSYS mechanical interface, where I can do this calculation? I see Stabilization Energy and strain energy only.<\/p>\n
