Upload a .fds file — you will see an estimated cost within seconds, before you commit to running anything. The simulation runs in the cloud and you only pay for the compute time it actually takes.
We read the &MESH sections and count the cells in each one — that is the basis for both the estimate and the machine sizing.
Meshes go to separate MPI processes on a dedicated server. No queue, no resource sharing.
The &TIME and &REAC sections give the simulated duration, and the CFL condition gives the real compute time.
The analysis happens locally in your browser. The file only reaches our server once you accept the quote.
The &MESH, &TIME and &REAC sections plus model elements (&OBST, &VENT, &DEVC) are read without uploading the file.
Runtime estimated from the CFL condition and a throughput of ~240,000 cell-timesteps/s per core.
You see the cost before the start — no subscription, no account.
The log refreshes every few seconds and the DEVC and HRR charts grow as the solver works. You do not have to wait for the end to see whether the model is heading the right way.
Run your first simulationCells and the estimated cost are worked out locally in your browser.
You accept the amount, and only then does the file go to the server.
A dedicated machine runs the solver while you watch progress live.
SMV files, slice planes, DEVC CSVs and the full solver log.
Every job gets its own virtual machine — no queue and no sharing compute with anyone else.
You pay for actual compute time and result storage. No subscription, no standing fees.
What you get
Smokeview visualisation
.smv files together with slice planes and boundaries — the full picture of how the fire and smoke developed.
Device data (DEVC)
CSV files with temperature, visibility and velocity readings — ready for assessing evacuation conditions.
Full FDS solver log
The complete run with solver parameters — for verification and project documentation.
Secure access for 60 days
You download results over a signed link; after 60 days they are removed from the server automatically.
Frequently asked questions
FDS input files with the .fds extension. We read the &MESH, &TIME and &REAC sections plus model elements (&OBST, &VENT, &DEVC) directly in your browser.
You pay for actual compute time and result storage — no subscription, no standing fees. You see the estimated cost before the run starts, and payment (Stripe, BLIK, Przelewy24) happens after the computation finishes. A VAT invoice is available in your account.
It depends on the cell count and the simulated duration. We show a runtime estimate with the quote, based on the CFL condition and a throughput of ~240,000 cell-timesteps/s per core. Every job gets its own dedicated compute server.
Yes. Each job starts a separate virtual machine — there is no queue and no resource sharing between your simulations.
The file is analysed locally in your browser and uploaded only after you accept the quote. The computation runs on servers in the European Union, and the machine is destroyed once the job finishes.
