In this work we have developed a new workflow to simulate snowflake and X-point target divertors in SOLPS-ITER. The workflow uses the external grid builder INGRID along with custom-built conversion routines to generate the required input files. The SOLPS-ITER source is also edited to identify a snowflake or X-point target geometry, without affecting present functionality in the code. Along with this novel workflow, the first SOLPS-ITER simulations of the X-point target will be presented. These simulations focused on a single null SPARC X-point target equilibrium and are compared to a similar single null standard SPARC geometry. Simple analysis using two-point model physics supports the validity of these novel simulations.
