Plasma heat transport modeling was performed using the ASTRA code. The LH deposition was calculated using the ACCOME and LUKE suite of ray-tracing and Fokker-Planck solvers, while the NBI deposition using the ACCOME and FAFNER codes. One of the principal features of NBI operation in COMPASS is relatively large ion orbit and charge exchange losses, which can including shine-through losses amount to 53% for NB counter-injection at low field B=1.2 T, I=170 kA and typical electron peak density of 3e19 m-3. For co-injection, the losses are lower: 10-25%. At the higher magnetic field, the total non-inductively driven current (bootstrap+LH+NB) is about 200 kA, substantially supporting the 250 kA feedback-controlled plasma current.
