Hi SimScale Support / Community, I am experiencing a repeated issue where a nonlinear static structural simulation remains at 0% and never generates a Solver Log . I would like to determine whether this is a compute/job-start issue or whether something in the simulation setup prevents the solver from launching. Simulation setup Analysis: Nonlinear static structural Geometric nonlinearity: enabled Materials: hyperelastic Contact: bonded Element technology: Automatic Mesh order: 1st order Mesh size: 74,572 tetrahedra, 20,780 nodes No Remote Force is used Boundary conditions consist only of one Fixed Support and two Pressure boundary conditions The loads are explicitly ramped with pseudo-time t rather than applied instantaneously Automatic boundary-condition ramping is disabled because the pressure ramp is explicitly defined in the formulas Run 1 – Nominal_Rest_Diagnostic_v1 Remained at 0% for approximately 47 minutes No Solver Log was generated I then requested cancellation Cancellation itself took approximately another 30+ minutes Final status: Canceled by user / Error 0% Event Log stated: “The run was canceled but the cancellation didn’t finish in time. No core hours will be deducted from your account for this run.” Final reported core-hour usage: 0.00 Run 2 – Nominal_Rest_Diagnostic_v2 The page was refreshed before starting the second run The simulation setup was left unchanged Again remained at 0% for more than 27 minutes Again, no Solver Log was generated I requested cancellation Final elapsed time was approximately 50 minutes Final status: Canceled by user / Error 0% The same cancellation-timeout message appeared in the Event Log Final reported core-hour usage: 0.00 The Event Log did not show a message indicating that the job was waiting for compute resources. I also contacted the in-product Ray Support agent. It confirmed that: standard Pressure boundary conditions applied to many faces do not normally cause this kind of long 0% delay ; the known preprocessing issue involving many faces mainly concerns Remote Force , which I am not using; if a job is waiting for compute resources, this should normally be reflected in the Event Log; there is no additional backend job-start status available to the user beyond the Event Log. My main concern is therefore that in two independent runs the solver apparently never reached the stage where a Solver Log was created . Could you please help clarify: Does the absence of any Solver Log after tens of minutes indicate that the solver/compute job never actually started? Is there anything in this setup that could block the solver during preprocessing before the Solver Log is created? Could this be a backend/resource-allocation issue even though the Event Log did not show a “waiting for resources” message? Would you recommend retrying the same simulation unchanged, or is there a specific setup item I should check first? I have attached screenshots showing: the final status of Run 1; the final status of Run 2; the mesh information showing 1st-order mesh, 74,572 tetrahedra, and 20,780 nodes .
