Implementing XFEM in ABAQUS using dynamic implicit step

Submitted by Vinod.Kushvaha on Tue, 06/10/2014 - 16:21

Is there anybody who has implemented XFEM in ABAQUS using dynamic implicit step? My model runs fine when I use 'static, general' step but when I change it to 'dynamic, implicit' I get following error message"The following XFEM cracks are failing to correctly generate and says crack domain contains invalid element shape." Please let me know what do I need to change in the model to fix this error.

Thanks so much for your help,

Sincerely,

Vinod Kushvaha

Hi everybody

I am a geotech engineer, I use a program Abaqus, I want to know

when I use tow layers of soil, each layer with their properties, when i use the contact between these layers

my question is; How i generat initial stresses without discontinuity between the two layers ?

Thanks
