Hello all,

I have tried going through the manuals to find out how I can change the coordinate system from rectangular (cartesian) to spherical and tried a number of ways with no success can anyone please offer any help on this.

Thanks.

 
Sorry the topic should say "Changing coordinate system from Rectangular to Spherical"
 
Would really appreciate some help and advice on this, thanks.
 
Hello,

how I can change the coordinate system from rectangular (cartesian) to spherical

If you would like define node coordinates in spherical coord. system type then use:

Code:
**
*NODE, SYSTEM=S
node_id, radial distance, polar angle (deg), azimuthal angle (deg)
**

If you want to define your bc or load in user coordinate system then:

Code:
**
*NSET, NSET=load-NSET
node_id
*TRANSFORM, TYPE=S, NSET=load-NSET
x_coord_a, y_coord_a, z_coord_a, x_coord_b, y_coord_b, z_coord_b
**

Thanks Bartosz for your helpful reply,

I wondered if there was a way of having abaqus convert the coordinates from cartesian to spherical/cylindrical without having to define all the nodes in the input file, i.e. maybe a feature in CAE to change from cartesian to spherical. Does anyone know if you can, I couldn't find anything in the manual.

Thanks
 
Hi,

I don't know is it possible with Abaqus/CAE, however there is one more keyword which can be helpful
to make conversion between coordinates systems. Please check *NMAP keyword.
