coordinate problem 1

[kaninchenofmersey]

Hi everyone,
this is my first post in this forum.

I am doing 2D hemisphere model pressurized by axial load on its surface by writing input file.

For node arrangement:
Node 1 is located at coordinate (43.59,90) at far right-edge of the hemisphere and center is at node 999 at origin.

The problem here is how i could locate node 101 (the far left-edge of the hemisphere) as the coordinate would be (-43.59,90)?

I got error message during analysis job as the coordinate could not be negative value.

Thanks for your help

I'd suggest that the error you see is because you have 2D axisymmetric geometry and as such you can't have a negative X value, or negative radius as it would be in RZ geometry.
