Default Error during get surface loads! in cfx

cfxuser1 is on a distinguished road
Hi everyone,

I am doing a fluid-structure interaction problem. I am getting this error message in the solver:
" Error during get surface loads: Total Force. Error Message: Read."

I don't understand why I am getting this error. I have run this same simulation before with a slightly different model and it worked. Now after changing the model a little bit, I am getting this error message. The model is basically a beam. The only difference between the two models is that the first one has one end of the beam (the flat face pointing in -x direction) as a fixed support and the second has that same end as a fixed support except for that end is attached to a circular object. So the circular face is a fixed support. i sketched it below so that it easier to understand

ist case:
fixed support>>>>> ----------------------------

2nd case:
fixed support >>>> O----------------------------

Could you please help on this issue.
