Zero Patient Dose Result in S3 Simulation
Quote from fai on February 1, 2026, 6:32 pmI performed the simulation by strictly following the steps described in Example 03 of the PRIMO user manual for patient dose simulation. Although the simulation finished without any explicit error messages, no patient dose distribution was generated. In the simulation log file, I found the following lines:
“Average time that took to change the geometry: 0.00 s
Time employed in simulation in the patient: 0.00 s
Time that took this report: 0.33 s”These values suggest that the simulation did not perform particle transport within the patient geometry, resulting in zero simulation time and no dose calculation. I would like to kindly ask for your help in understanding why this issue might occur, despite following the workflow described in Example 03. Any advice or recommendations you could provide would be greatly appreciated, as I am trying to obtain a valid patient dose distribution for further analysis. Thank you very much for your time and support. I look forward to your response.
