use PARAM,CHECKEL,NO. This may, however, cause very poor results.

Codiak,
to bypass element quality checks (except essential validity checks) , use PARAM,CHECKEL,NO
This is created in the control cards panel,
It is advised however that you improve the quality of your mesh, see element quality checks and fixing tips in the student guide and the training center here - http://training.altairuniversity.com/modeling/element-quality/
