A matlab code for 2-dimensional finite elemnt method.

You can run main.m directly

Inp files:

1. NLIST.DAT
2. ELIST.DAT
3. FixNode.dat
4. NodeForce.dat
5. press.dat

You can generate the inp files by ANSYS or Abaqus.

-------- for inp files------------

If you select Ansys, you can use the *.mac files to generate all the *.dat files automatically.

Provide all ANSYS secondary development files:

1. uget.mac
2. umesp.mac
3. ugetfix.mac
4. ugetforce.mac
5. uexportPress.mac
6. transPress.py (necessary to translate the press.txt)

You need to follow these steps to automatically generate the input file:

1. Establish a FEM model in ansys and apply boundary conditions
2. Place all *.mac files into the current folder
3. Enter: uget,2 in the ANSYS command window
4. Run transPress.py (you need to install python3.5+ in advance)
