I am doing a uniaxial tensile test of a hyperelastic sample (60mm*50mm*1mm), one with a notch and another without a notch. The uniaxial tension for a notched sample is not converging (for an un-notched sample it converged easily), I am using SOLID 285, pure tetrahedral mesh, large deformations on, quasi-static on, used steps and substeps for slow loading, fine mesh at the tip of crack & followed the videos and other suggestions by Ansys, however, I am getting high elemental distortion error. <\/p>\n
