• Crash on "SetMember" in Matrix class when getting the internal force
• Crash on "mDkt" in GetLocalInternalStressAt in the DktHelper class

To Reproduce Any triangular shell case

Could you please also put stack trace something of exception (I mean Exception.StackTrace property) Thanks

E.g. for the SetMember-bug: Exception: Invallid column or row specified StackTrace (reduced): at BriefFiniteElementNet.MatrixException.ThrowIf(Boolean condition, String message) in \BriefFiniteElementNet.Common\MatrixException.cs:line 48 at BriefFiniteElementNet.Matrix.SetMember(Int32 row, Int32 column, Double value) in \BriefFiniteElementNet.Common\Matrix.cs:line 647 at BriefFiniteElementNet.Matrix.set_TheMember(Int32 row, Int32 column, Double value) in \BriefFiniteElementNet.Common\Matrix.cs:line 453 at BriefFiniteElementNet.Matrix.FillColumn(Int32 colNum, Double[] values) in \BriefFiniteElementNet.Common\Matrix.cs:line 1832 at BriefFiniteElementNet.ElementHelpers.CstHelper.GetLocalInternalForce(Element targetElement, LoadCase loadCase, Double[] isoCoords) in \BriefFiniteElementNet\ElementHelpers\CstHelper.cs:line 284 at SolverTest.Testcases.S3ShellTester.writeDataTriangleElement(Model model, LoadCase testCase) in Validation\Code\SolverTest\SolverTest\Testcases\S3ShellTester.cs:line 351 at SolverTest.Testcases.S3ShellTester.Model1Test2() in Validation\Code\SolverTest\SolverTest\Testcases\S3ShellTester.cs:line 84 at SolverTest.Form1.button2_Click(Object sender, EventArgs e) in Validation\Code\SolverTest\SolverTest\Form1.cs:line 38

Thanks for report, so it shows CstHelper.GetLocalInternalForce() throws exception. Will check it...

Seems error is gone for now, can you please do a check again? Thanks
