Hy i am doing soil pipe interaction in abaqus .when i increase the size of the seeds during mesh beyond (0.75) Abaqus give me error that speed to wave deformation exceed at a certain node? when i do it manually for each edge by selection number of seeds then the solution converges but manual process is time consuming ?will anybody please explain that phenomenon.( i have attached a snapshot of problem)
Dear Arsalan Ahmad,
Could you please explain your model a bit in detail? For example, do you perform displacement controlled analysis (ex. pipeline crossing faults)? What type of interaction do you use between pipe and soil (surface to surface contact, general contact, etc.)? If you provide more information about your model, I may help you.
Best regards

Sir it is load based analysis in which i applied a load with linear amplitude curve (Fexure load on the pipe)and the interaction i am using is surface to surface contact )
@Hasan Emre Demirci sir i have done nonlinear analsis for buried pipeline for both cases of (load case and pipeline line crossing fault(displacement analysis) bur sir it was ok but when i do it for linear then it show me error about certain mesh size
