Ls-prepost error of shell element, that violates heuristic shape criterion?

11 June 2021 0 3K Report

Warning 21129 (STR+1129)

shell element, ID 1479 violates heuristic shape criterion

area/(longest diagonal)/(longest diagonal) equals: 5.0000E-02

which may be too small (< 0.1) to permit a stable calculation.

I am getting these type of errors despite changing elements from shell to shell_Thickness. Please help me solving this problem
