Newmark method for elastodynamics finite element 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)
