I have made this half-wing through Solidworks and imported to Ansys ADPL. I want to do a Structural Analysis , so i have put some pressures and some displacements - supports (all DOF's value 0) in some lines of the wing contour. After i try to solve the problem i have an error and some warnings , *ERROR* : There is at least 1 small equation solver pivot term (e.g., at the ROTX
degree of freedom of node 360). Please check for an insufficiently
constrained model.
I have tried many different displacements with different DOF's but i get this error constantly.
I dont if the error is caused by faulty displacements or faulty mesh or geometry so im gonna add some files like the SW model ,the .lgw file , the .igs file and the .err file to tell me your opinion.
Thank you in advance.
It happened once with me and i found one free element in the model. so i would suggest, pick that node number and do esln, nsle..... and check if that element has some constraint or free. if it is free then apply some constraint (DOF etc) and rerun.
I tried to merge everything with nummrg, all , and it worked
thank you guys
