Hi @Artyom-K You could instead write an MAPDL input file then read that in, but then you would need to retrieve the node X values collected. I think it might be better to instead gather the nodes to an array and parse through that for the needed information. Please try this example: from ansys.mapdl.core import launch_mapdl
import numpy as np
import os
path = os.getcwd()
mapdl = launch_mapdl(run_location=path)
mapdl.clear()
mapdl.prep7()
mapdl.n(1,0,0,0)
mapdl.n(2,1,0,0)
mapdl.n(3,2,0,0)
mapdl.n(4,3,0,0)
mapdl.n(5,4,0,0)
mapdl.n(6,5,0,0)
mapdl.n(7,6,0,0)
n_list = [2, 4, 7]
node = mapdl.mesh.nodes
node_num =mapdl.mesh.nnum
nodes_x = []
for i in n_list:
print("node " +str(i)+ " x is " + str(node[np.where(node_num == i)[0][0]][0]))
nodes_x.append(node[np.where(node_num == i)[0][0]][0])
nodes_xWhich will result in:
Then don't forget the mapdl.exit() |

Hi @Artyom-K The queries module is not compatible with However you are right, that the If I were you, and needed speed, I would just do: nodes = mapdl.mesh.nodes
def nx(i):
return nodes[i,0]
def ny(i):
return nodes[i,1]
def nz(i):
return nodes[i,2]
# and then:
for i in nlist:
x = nx(i)This way you avoid multiple calls to the MAPDL instance. |

Hi @mikerife I would like to suggest a small improvement to your snippet: >>> # Assuming this are the node ids you want to return
>>> n_list = [2, 4, 7] # mapdl indexing
>>> n_list_ = np.array(n_list) - 1 # python indexing
>>> node = mapdl.mesh.nodes
>>> nodes_x = node[n_list_]
array([[1., 0., 0.],
[3., 0., 0.],
[6., 0., 0.]]) |

@germa89 Thanks! I'll have to dig into that more - I'm wondering if that will work if there are gaps in the node numbering (which is always a concern of mine). Mike |
It is a VERY valid concern honestly. In case the nodes are not contiguous: from ansys.mapdl.core import launch_mapdl
import numpy as np
import os
path = os.getcwd()
mapdl = launch_mapdl(run_location=path)
mapdl.clear()
mapdl.prep7()
# node ids are the same as the x coordinates
mapdl.n(1,1,0,0)
mapdl.n(2,2,0,0)
mapdl.n(3,3,0,0)
mapdl.n(6,6,0,0)
mapdl.n(7,7,0,0)
mapdl.n(10,10,0,0)
mapdl.n(12,12,0,0)
n_list = [2, 7, 12]
nnum = mapdl.mesh.nnum
nodes = mapdl.mesh.nodes
indices = np.in1d(nnum, n_list)
mynodes = nodes[indices,:]
assert np.allclose(mynodes[:,0], n_list)You will love numpy.in1d from now on! 😉 |
