Write ‘inp’ file#
Consider an FEM problem of a plate with a circular hole on the edge (see figure below).
An example of ‘inp’ file with some output commands is given below :
****calcul % beginning of a FEM problem (note no indent)
***mesh small_deformation % defines the element formulation
***resolution newton % resolution method, and its options
**sequence % loading sequence
...
***bc % definition of boundary conditions
**impose_nodal_dof % creation of BCs
top U3 3. time % impose U3=3*time on 'top' nset
x=0 U1 0.0 % ...
y=0 U2 0.0 %
z=0 U3 0.0 %
***output % specifies output options
**save_material_rotations
**verbose % verbose output to see the front size etc
**contour % contour output for extrapolated integ->nodal
**contour_by_element % contour values of integ values element by element
**value_at_integration % these are the REAL stresses and strains.
**curve % curve output into default file plate.test
*node_var node2 U2 % print U2 values for node2 nset
*nset_var top U2 % print the applied load (F2) over the surface
% defined by the node set 'top'
***material % material definition
*this_file % the behavior is defined within the same file
****return
