,okay I will read the link you shared in order to avoid using MPC184 elements which use lagrange multipliers. I just want to erase all the ways which may lead to mandatory use of Sparse (Direct) solver within my model, because I don't have enough RAM to do that. Not using Lagrange Multipliers in MPC184 elements has its own drawbacks as well, sir? What would you say?
I decreased the total number of elements within my model, so now they are 548,769 elements (which includes only solid, shell and beam) and a total of 1,129,629 nodes within my model. For this, I got something inside solver output as shown below.
I mean yes, for the 'Numer of total nodes', I can understand that why they are a little bit higher than those within my model (because some extra pilot nodes maybe created during solution). But for the 'Number of solid elements', they are equal to those within my model but my model has these elements which are not just solid; it also inlcudes shell and beams. So I don't know why does the solver classify all of these under the name, "solid elements'' within solver output file.
Anyways, the above picture can easily tell me the total number of contact elements which are created within my model, and why are these the reason that I see dramatic difference between the 'Number of total elements' in solver output file and those within my actual model. Would you suggest something to decrease these total number of contact elements, because these are the reason why RAM requirement drastically soars.
Plus, what does Total CP and Average CP means?
