Hey all,
I am trying to simulate the deflection of a half-sphere, with ALE Fluid-structure interaction, stuck on the bottom surface of a microfluidic channel (height = 50 um and width = 300 um) and it works fine with mean inlet flow velocity 10 cm/sec (I see the sphere deflecting), but when I try to increase it to 15 cm/sec, for example, I got an error, stating:
"Non-linear solver didnt converge. Attempt to evaluate real square root of negative number..."
And then a huge mesage follows...
I tried to make the mesh finer, to use adaptive mess, or to use auto-meshing, but every time I had the same error.
So, what do you suggest me to do in order to have higher velocities?
I am also trying to attach the file, but it says it is too big for attaching...
Thank you alot in advance.
