Dear all
I need help for the following warning:
The ratio of deformation speed to wave speed exceeds 1.00 in at least one element. This indicates the error with the model definition.
For example in massage file I found:
The maximum ratio of deformation speed to wave speed is 0.30531 in element 1548 of instance COMP-90-1 at increment 69892.
The maximum ratio of deformation speed to wave speed is 1.2073 in element 16997 of instance COMP-90-1 at increment 70069.
I thanks all
Dear Semayat,
please provide me more info on your model. Usually this can be either to poor mesh, too big deformation of the element(if your element deforms too much try adding damage model and use STATUS variable to delete it) , wrong material definition etc.
Another advice is re mesh the model, check the contacts(if you have any initial contact clashes , STRAINFREE variable will be plotted in the zero increment) and try mass scaling.
