Hello every one

 

when I run the OptiStruct in the .out file i found these warnings  . can i cancel this option under OptiStruct ?

 

 

 

Element # 6, element type TETRA.

 WARNING - Outside of recommended range: Face Skew Angle =    76.060    

           upper limit =    75.000    

 WARNING - Outside of recommended range: Face Vertex Angle =    7.4711    

           lower limit =    15.000    

 WARNING - Outside of recommended range: Edge Angle =    81.129    

           upper limit =    75.000

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.alta...lement-quality/
