In materials that undergo extremely large deformations, such as soft foams, an element may become so distorted that the volume of the element is calculated as negative. This may occur without the material reaching a failure criterion. There is an inherent limit to how much deformation a Lagrangia...
negative volume and also delete solid elements whose current time step drops below the threshold of dtstart*DTMIN. Try ERODE=1 and DTMIN=0.5. If all the elements erode at some point during the simulation, it means all those elements have met at least one of the two criteria mentioned ...
If you use the hexahedral element, that is present there is no effective way, you can try *ELEMENT_SOLID_EFG, the requirements of the machine will be relatively higher. Solution of Q1: material negative volume (comprehensive and effective) Methods to solve the negative material volume In the ...

Re: negative element volume (CFX-10.0) #5 Chirag Jayswal Guest Posts: n/a While meshing in ICEM, after creating prisms, do not smooth "Penta" elements. Smoothing "Penta" sometimes creates this problem of negative volume element creation. You can smooth all other elements. Create a new mesh...
