I have made a surface model of a bike chassis and used knot surface command to bonded for the surfaces. When I start to do static study, after like 4 to 5 hours, it displays the error static model failed. The meshing does not create any problems. I have located fixtures and used the appropriate material for the chassis. Under the shell manager, I have chosen the 'Thick' shell option and given 0.15 cm thickness for the surfaces. However, it does not solve the analysis.

Please help me on this. I have attached the solidworks file.

Regards Hamid.
