1 year ago Agreed on all points.
- Line 78 of main_nonlinear changed to function pointer
- setDefault has replaced the error with a warning and informs the user when the pointer is not specified.
- Test cases no longer use the setDefault to set the pointer and the pointers have been specified in all cases.
What?
Replace the direct reference to the getK function with function pointers to a new file that calculates the tangent matrix and internal forces vector. Function pointers were also created to the getStrain function.
Why?
To create a framework using the non-linear Newton-Raphson solver that enables a modular swapping of different tangent matrix calculations for different non-linear material types.
How?
The user specifies the name of the function they plan to use to calculate the tangent matrix and internal forces. The main file uses the feval function to evaluate this function.
Testing?
MainConfigFile, RunTests
Anything else?
I tried to future-proof the inputs to the general tangent matrix calculation function by including additional inputs that are not currently in use. These include d-vectors from previous timesteps, the linear M and K matrices, and timestep sizes from the current and previous timesteps.
