Hi!
I believe you can insert very easy a "point" feature in the ansys design modeler. Workbench creates automatically a spot weld from this points. I will have a look at ANSYS at work tomorrow.

Nodal forces are applied in nodal coordinate systems!
You have to rotated the node coordinate systems via nrot command in to your local coordinate system!

Hi!
First you have to read the file into ANSYS. The best way is the usage of the *tread command to do this. *vread or *mread are the other ways. By using the *tread command you do'nt have to define the format of the file :o)
Of course you must define a table or an array before reading the...
The *get command is the most powerful ANSYS APDL command!
Always look in the help (help,*get)!
You can get a lot (almost all) informations of ANSYS database with the *get command!
*get,n_num,node,,count !count of nodes
*get,n_max,node,,num,max !maximum node number (selected)...
Ok.
What you are trying can't work.
Area 4 belongs to volume 1 and area 7 to volume 2.
What you need is the vglue command.
finish
/clear

ready :o)
But attention!
You get some bad (peaked)...
It must be work!

To connecting two ore more parts with different meshes, the better way is the use of bonded contact with mpc-algorithm.
These elements create also constraint equations but these equations will be updated at each iteration. Standard ces are the same at all time. If you have large deformations /...
Hi!
1.)If you use
numstr,area,arinqr(0,14)+1
the resulting area numbers beginning with the maximum area number plus one.
2.) New areas have none attributes. If you give the input (unmeshed) areas an attribute (real,mat,type,esys or secn) with the aatt command, the new area attributes are...
You have worked with arrays before?
For example you have 10 nodes. (node numbers are: 11,16,27,101 ...).
You can define a vector with the *dim comand.
*dim,name,array,10,2
and fill the vector with node numbers and contraints.
may be:
name(1,1)=11
name(1,2)=0.1
name(2,1)=16
name(2,2)=0.2...
Hi!
You can create your own file.
For your example copy the following lines in to the ANSYS input line!
LSEL,S,,,1
NSLL,S,1
*create,hhhh,mac
!maximum node number
*get,n_max,node,,num,maxd
!node count
*get,n_num,node,,count
!temporary array
list_tmp=...
Are your contact pairs ok?
Contact and target elements must have the same realconstants!
esel,s,real,,?
Also looking for the elementnormals of the contact elements!
esel,s,real,,?
/psym,esys,1
They must be opposed!
