In RF-FORM-FINDING, I cannot define the prestress separately for warp and weft. How can I activate it?


The directions of the warp and weft are linked to the axes of the surface. With the default setting, only an isotropic prestress can be applied. If the axes are aligned, orthotropic or radial prestress will be available as well.

The procedure is demonstrated in the video.
