PROGRAM STOPPED: ERRORS DURING ELEMENT QUALITY CHECK?

I am attaching the saved hm file of the model. The model is Heat Sink and we need to perform thermal stress analysis on it and the mesh is tetra elements.

The amount of memory allocated for the run is 800 MB.
This run will use in-core processing in the solver.

Element # 53622, element type TETRA.

*** PROGRAM STOPPED: ERRORS DURING ELEMENT QUALITY CHECK.

I am getting this error continuously even though quality is clean. Can anyone identify what's the mistake and provide a solution?

    Your elements are not 'clean'.

    Just open the .out file and you will see some of the errors by the solver.

    You should review your elements, preferably.

    But, if you want to ignore some of the errors (by your own risk), you can use PARAM, CHECKEL, NO as mentioned also in the .out file. This will bypass the errors which are not critical.
