Yes. ANSYS Fluent's GPU solver mode is validated by ANSYS on specific certified GPU models and driver versions. When Fluent's GPU solver is invoked on a GPU that is not on the ANSYS validated hardware list for that solver mode — which includes consumer GPUs — the software produces driver warnings indicating that the GPU is not in a supported configuration for that solver. The solver may still run, but it operates outside the validated environment. For engineering firms and research organisations where solver output provenance matters — where results need to be produced in a documented, validated configuration — ISV certification on the GPU is a requirement rather than a preference. The RTX 4000 Ada on the Forge H runs the certified driver stack validated for ANSYS Fluent GPU solver operation. The specific ANSYS Fluent versions for which GPU solver support is certified should be confirmed with Kevin before ordering, as supported version lists are updated with driver releases.

The G6 Forge M uses a Core Ultra 9 285KF with 64GB DDR5, an RTX 2000 Ada 12GB ECC, and dual 2TB NVMe. The Forge H uses the same processor with 128GB DDR5, an RTX 4000 Ada 20GB ECC, and a 2TB plus 4TB NVMe configuration. The practical differences are: 128GB versus 64GB for large mesh solver cases where 64GB becomes insufficient; 20GB versus 12GB ECC VRAM for solver cases that exceed 12GB GPU memory; and ANSYS Fluent GPU solver certification, which the 4000 Ada carries for the GPU solver pipeline that the 2000 Ada does not cover at the same scale. The Forge M is correct for ANSYS Mechanical FEA with CPU solver, mid-scale CATIA, and large SolidWorks assemblies within 64GB. The Forge H is correct when GPU solver certification, 20GB ECC VRAM, or 128GB system RAM are required.

Yes. The RTX 4000 Ada 20GB performs competitively in Blender Cycles OptiX, V-Ray GPU, and Redshift for production architectural and product rendering — particularly relevant for architectural visualisation practices that work in CATIA or SolidWorks alongside rendering. 20GB VRAM covers most production rendering environments without texture downscaling or scene simplification. The dual-use case is well-served by the Forge H: the certified driver stack handles the CAD and simulation workflow, and Blender and V-Ray GPU use the same hardware without configuration conflict. For studios that specifically need ISV certification alongside rendering capability — a Dassault hardware requirement, for example — the Forge H provides both in a single machine.

ANSYS Fluent GPU solver VRAM requirements depend directly on mesh size. As a general guide: a 1 million cell mesh requires approximately 3 to 4GB GPU VRAM for the solver; a 5 million cell mesh requires approximately 10 to 15GB; a 10 million cell mesh can require 20GB or more depending on the physics models and solver settings. The RTX 4000 Ada 20GB ECC covers most professional CFD workflows up to and including large mesh cases in the 10 million cell range. For mesh counts significantly above 10 million cells, call Kevin and describe your typical mesh size — the 20GB VRAM figure and your specific ANSYS Fluent GPU solver configuration should be confirmed before ordering. Note also that solver VRAM requirements depend on the physics models activated: multiphase and reacting flow models increase memory demand.

Build time is 3 to 5 working days from order confirmation, including the 24-hour stress test at sustained GPU solver load and the 128GB DDR5 memory profile verification applied before dispatch. Delivery to UK mainland addresses is free and fully tracked. Call Kevin on 01902 714533 before ordering to confirm the specific ANSYS and COMSOL versions supported by the current certified driver, and to verify the timeline if you have a project or submission deadline.
