Dear all,
I am simulating a thin plate which has 0.2 mm (millimeter) thickness, 100 mm as length and 60 mm as width. Because of having very small thickness, mapping is failed. I have tried several ways to generate a fine mesh but they did not help me. It would be appreciated if you let me know your idea how to solve my problem.

hi,
what is the exact error message. the problem may be arise due to large time stepping that creates negatives cells at fluent. try to reduce time step and add damping in mechanical solver.
regards.

Thank you very much for your answer. My problem is that the node and area mapped are not 100% as you can see below:

+--------------------------------------------------------------------+
| MAPPING SUMMARY |
+--------------------------------------------------------------------+
| Data Transfer | |
| Diagnostic | Source Side Target Side |
+----------------------------------+---------------------------------+
| Data Transfer | |
| Percent Nodes Mapped | N/A 100 |
| Data Transfer 2 | |
| Percent Nodes Mapped | 45 30 |
| Percent Area Mapped | 28 27 |
+--------------------------------------------------------------------+
