How can I loosen the too tight tolerance on FLUID130 spherical radius?
I am getting the error message below.
*** ERROR ***
Node no. 7576 of the FLUID130 Acoustic Absorbing element 17664 should
lie on a SPHERE of radius 0.8; instead lies at a radius of 0.800097109.
Ensure that the radius input through the element Real Constant
matches with that of the absorbing boundary.

There is no way to loosen the tolerance, but a workaround is to move the nodes to exactly 8 inch radius with the commans below. The tolerance seems overly tight, but if there is no solid model it would be possible to move the nodes to the radius of 0.8 using the following commands: csys,2 nsel,s,loc,x,0.8 nmod,all,0.8 nsel,all csys,0 |
