Hi,
can any one help me solve these errors from my graduation project model? Emergency~~ Many thanks!
The errors are:
Division by zero.
- Function: /
Failed to evaluate variable.
- Variable: comp1.emi.D13
- Defined as: (comp1.emi.nu*comp1.emi.E)/((1-(comp1.emi.nu*2))*(comp1.emi.nu+1))
Failed to evaluate variable.
- Variable: comp1.emi.Sl11
- Defined as: (comp1.emi.D13*comp1.emi.eel33)+((comp1.emi.eel11*comp1.emi.D11)+(comp1.emi.eel22*comp1.emi.D12))
Failed to evaluate expression.
- Expression: d((-comp1.emi.Sl11*test(comp1.emi.el11)-2*comp1.emi.Sl12*test(comp1.emi.el12)-2*comp1.emi.Sl13*test(comp1.emi.el13)-comp1.emi.Sl22*test(comp1.emi.el22)-2*comp1.emi.Sl23*test(comp1.emi.el23)-comp1.emi.Sl33*test(comp1.emi.el33))*(dvol),{test@6})

Hi Mirror,
This error will occur if you set Poisson’s ratio to 0.5 for a perfectly incompressible material. There is division by 1-2*v in the denominator which is a division by 0. If that is the case use a slightly lower value such as 0.499.
