Crack propagation in ANSYS vs. ABAQUS

Submitted by morteza2013 on

Hello dear friends,

 

I am Morteza, PhD student of Materials Eng. I have this course of Computational Modelling with Abaqus this semester. My Professor asked me to compare different approaches of crack growth analysis in Ansys and Abaqus including different formulations, procedures,... . He recommended to check the user's manual in these two softwares.

I would like to appreciate it if anybody could help me with this task as I am absolutely new in this field.

problem of I/O in UMAT

Submitted by zhouyinhua on

Hi 

Has anyone met the problem that if  adding the I/O (just reading
externals or writing externals) in UMAT, the computing speed becomes quite
slow, but the CPU occupied by the ‘standard’ process is few, sometimes even keeps zero all
the time. The I/O is quite simple, just using the 'OPEN' , 'READ' and 'WRITE'.

 That would be great if anyone knows the reason for this problem.

 Thanks and Regards

Yinhua
