Dear all,

I wanted to ask how to resolve the error of getting some element negative or zero or small area, Like with the same mesh with simple elastic or elastoplastic analysis it (abaqus) is not giving the same error . Only when I am using phase field with subroutine I am getting this error .

Note: The specimen I am running the simulation is Compact tension (CT) specimen in 2D .

One of the probable solution I am gonna work on is to ,"Mesh the specimen in Hypermesh" but I do think that it can be done simply in abaqus cause CT specimen is not that complicated specimen to mesh in abaqus with good mesh quality to work with .

Thanks for any future help and also if i find the solution to my problem I will share it in here in the answer to my own question .
