Could you say anything about which meshes are compatible and incompatible with J-Integral output requests? I used the following mesh controls and element type for the circle around a crack. - quad-dominated shaped elements - mesh technique: swept - element type linear My J-Integral calculation failed. An error message stated Error in job NewJob1: Triangles, Tetrahedra and wedges may not be used in a contour integral region. 33 elements are within a contour region. The elements are identified in element set ErrElemIncorrContInteg. With my mesh controls, the generated mesh included some triangular elements (the elements closest to the singularity. I created a circle around the singularity with 34 radial lines, therefore 33 slices - which explains the referece to 33 elements above..) which seems to be what the error is talking about. Why does J-Integral calculation fail because of this? When I use a quad shaped grid of mesh elements around the crack tip i dont have a problem. However I know that i should mesh a circle around the crack tip, not a grid Do you have any recommendations of how to solve this issue?
I am getting this error Error in job Jintegral: The area of 18 elements is zero, small, or negative. Check coordinates or node numbering, or modify the mesh seed. The elements have been identified in element set ErrElemAreaSmallNegZero.
I want to learn Abacus software related to my research work and my topic is Fatigue behaviour of headed stud shear connectors in steel concrete composite beams
Thanks for support
Very helpful video
Thank you very much

Dear Sir is the angle and length of crack effecting on J value, Thank you in advance
Geometry of the part and crack affect the stress field and consequently all the contour integrals.
