AbstractFor the modular non-planar coil system of a Helias reactor (HSR) the distributions of the magnetic field and the coil forces are calculated by means of the EFFI code. In order to support the magnetic forces a scheme of mutual support of the coils is applied. The pancakes of the coil winding pack of each individual coil are embedded in a strong coil housing of stainless steel. Linear and nonlinear finite element computations are done with half a field period, using the ANSYS code and taking into account the stellarator symmetry. The mechanical stress and strain distributions inside the winding pack and the coil structure are analyzed.
