*viscoelasticity requires the use of either *elastic, *hyperelastic, *anisotropic hyperelastic or *hyperfoam 13831 elements have been defined with zero hour glass stiffness. You may use *hourglass stiffness or change the element type. The elements have been identified in element set ErrElemZeroHourGlassStiffness. 15083 elements are missing elastic property reference. The elements have been identified in element set ErrElemMissingElasticPropRef. The area of 3 elements is zero, small, or negative. Check coordinates or node numbering, or modify the mesh seed. The elements have been identified in element set ErrElemAreaSmallNegZero. The elasticity for time domain viscoelasticity must be defined by the *elastic,type=isotropic, *hyperelastic or *anisotropic hyperelastic option Analysis Input File Processor exited with an error. 出现这个错误是怎么回事啊，该如何去修改，谢谢你！
