You can import .inp file generated by Abaqus into Matlab and try reading the lines containing nodal information.

Thanks.

You can run this as .py script:

from abaqus import *

from abaqusConstants import *

import __main__

import part

import assembly

import mesh

x = []

y = []

z = []

Nodeset = mdb.models['Model-1'].rootAssembly.instances['Part-1-1'].nodes

j = 0

for i in Nodeset:

x.insert(j,i.coordinates[0])

y.insert(j,i.coordinates[1])

z.insert(j,i.coordinates[2])

j=j+1

print (x,y,z)

You will have x,y,z printed, which you can copy to Matlab. Make sure you use matching model name and instance name in Nodeset line (you need to have an instance).

Regards,

Export your model as '.inp' file after meshing. Write a program in MATLAB which should read your '.inp' file and store the mesh information in two arrays for nodal coordinates and element connectivity.
