-====== Non-Linear Modeling ======
+====== Non-linear Modeling ======
+ACS SASSI has a process to simulate a model with non-linear materials.
+===== Creating a Non-linear Model =====
+==== Starting From a Linear Model ====
+ACS-SASSI User Interface has commands to change a Linear model so it can be used in a non-linear analysis. The process is begins with creating 2 copies of the linear model in User Interface memory.
+=== Example(s) ===
+== Creating a Nonlinear Panel Model ==
+<code>
+* General nonlinear model creation
+* Load a starting model and copy it to create a Panel Model
+ACTM,1
+INP, Model1.pre,C:/Models/Demo/ *Starting model
+* Move to copy of the model to create a panel model later
+CPMODEL,2
+*delete the shell groups from this model
+GDEL, ...
+GCOM
+ACTM,2
+*create the panel model
+WALLFLR
+* further refine the panels
+...
+ACTM,1
+*Recombine the model panels with the non-shell elements
+MERGEPANEL,2
+</code>
+**Note(s)** : General Nonlinear example command list or *.pre file. The first ellipsis is a list [[com:GDEL]] commands to remove the shell groups from the initial model. The second ellipsis will contain different commands to split and modify the shell groups depending on the model.
