Dear all,

I am doing transient FSI modelling in arteries. I've come across the following error at the beginning of the solution.


*** ERROR *** CP = 44.991 TIME= 17:09:21
Time increment for solid field analysis, 1 is greater than time
increment, 1.E-02 for multifield analysis.

Error during setup - Skipping the remaining MultiField analysis.

The interesting thing is that I have been doing the transient FSI modelling for the last 5 months and everything was going well till this morning that I got the above error message. I am really confused because I exactly set up the FSI model this morning as I already did. It seems that above error is due to the time step inconsistency between fluid and solid; however, I checked the time steps, both fluid and solid time steps are same.

I would be too happy if anyone helps me.
Regards,
AshtonJ
