Fully 3D model of strongly asymmetric tokamak core, based on boundary integral method approach (i.e.characterization of ferromagnet by its surface) is presented. The model is benchmarked on measurementson tokamak GOLEM, as well as compared to 2D axisymmetric core equivalent for this tokamak, presentedin previous work. Linearized model well describes quantitative characteristics of BRfield, generated bypoloidal field coils located close to core central column, and distorted by ferromagnet. A discrepancy isseen between linearized form of model for BRfield generated by coils under the transformer limbs andthe measurements. Future work will thus include implementation of the non-linearity effects in order tofurther investigate this issue.
