#168 Nastran SOL 106 vs SOL 400
It is always challenging when it comes to nonlinear analysis, either it is geometric, material, or contact nonlinearity using SOL 106 in Nastran. For Advanced nonlinear analysis, SOL 400 is a new approach to solve the different types of nonlinear analysis. SOL 400 is having some advanced features like large displacement and large strain solutions. Also, it supports advanced MARC elements along with traditional Nastran elements which supersedes some Nastran solutions like 106, 129, 153, and 159 solutions. For Contact non-linearity, CGAP modeling can be avoided where SOL400 promotes a realistic contact approach.
MSC Nastran SOL 400 enables significant time savings by allowing for an easy transition from linear to nonlinear analysis inside one tool, and more convenient model sharing between multiple groups eliminating error-prone transition and duplicate work. SOL 400 enriches in a set of capabilities like geometric, material, and contact non-linearities. As a result solution 400 is better equipped with handling geometric, material, and contact non-linearities with better performance and is flexible in handling the solution parameters with different types of complex nonlinearity where always the results are accurate and more realistic.
