Look for special characters in your model and/or path to your file. Some parts of CFX don't handle them well, so be sure to only use [a-z][A-Z][0-9] on your names. Steer clear of things like , , , , , etc.

Or just post your entire CCL here so we can take a look at it.

Hi,
I am not using any special charcters in names. I do not know what is causing this error. I have attached the CCL. Please have a look if you had a chance.

A comment:
No need to use things like sin(43.7*pi/180). Much better to just say sin(43.7[deg]) and let the solver handle the units conversion.

Can you post your output file as well? And an image of what you are modelling.

Thanks for the comment Glenn. The rods are moving upwards, all surroundings are wall. Since I get the error, I cannot produce output files

Have you done the debugging suggested in this FAQ: http://www.cfd-online.com/Wiki/Ansys..._went_wrong.3F

Ok guys, I contacted the ANSYS support team and they told me that since the rods are extended all the way to the boundaries it fails to remesh. Now I have left a very small gap on each side of the rods and it is supposed to run just fine as ANSYS guy told me.
it works fine and even remeshes the domain in the first loop but then I receive this error

Guys is there any scripting example for remeshing problems?
I need to know do I have to have the commands for writing the mesh in the script?
more importantly
If each time the position of the moving object is going to change and in the script ICEM is going to put the object in its original location how it is supposed to mesh the new domain?
All I am saying is that in the script the location of the moving object is FIXED so in every timestep the ICEM is going to put the box right in the same location as before. Isn't it? I think that is why I am having awful number of errors.
That is why I need to take a look at some scripts that have been written for this case.
