Does anyboby know if TGrid is able to run in parallel??

No it is not... Why do you need it?

I need it for refining a model in two processors. What is the principal reason because Tgrid does not work in parallel??

Why do need to refine it on two CPUs? Speedup reasons?

The reason is that FLUENT/ANSYS has not yes parallelised it....

speed up simply, and I have the doubt simply, because if fluent can run in parallel. why Tgrid doesn't?

Fluent solver runs on parallel but not the Post processing. You can only solve using parallel computation not setting up the model and pre-processing the results.

You can in fact setup, solve and post process in parallel in Fluent. Some functionality is restricted when doing post in parallel such as deactivate cell zones on partitioned grid but for the most part you can do all 3 in parallel and not just the solve.

TGrid is only a serial product but using 64 bit you can generated >100million cell meshes. Note that ANSYS ICEM can be used in parallel on a multi cpu machine.

icem can be used in paralell only for tetrahedral meshing

Thank you for the onformation Red Lemon! Fluent post and set up lienses do get opened on parallel. But while keeping note of the CPU usage, I could not see the CPUs (nodes) loaded other than the master one. So thought the other CPUs are just connected but not used. But it may be because of size of my model (only 11 million hybrid cells!).
