Dear Afzal,

 

You there are 2-3 ways to solve this Meshing Quality Criteria -

 

1. Refer the Manual Quality improvisation methods 

Tools > Check elem > Select respective quality Criteria 

 

Save Failed > Mask > Elements Retrieve >  Mask > Reverse 


Shift + F2 ( Add nodes ) & rectify them.

 

This method have been explained in "3-Meshing Video" you can use the similar process for 2D shell elements too.

 

 

2. Refer to QI Mesh Creation Methods

 

PFA document which will help you to generate QI Mesh generation.

 

 

3. One more method is there. It is ok, if  you are running it base run to know the behavior of your model. But we do not recommend for final run. ( You need to have reasonable Mesh Quality to start the run skipping element Criteria Check )

 

Analysis > Control Cards > Param  > Mark "CHECKEL" > say "NO"  ( This will start the run without referring to Quality Criteria, but reasonable mesh quality should be present  )
