ERROR RDMORLYR: memory alloc error - D-Flow Flexible Mesh - Delft3D
intro story D-Flow FM
D-Flow Flexible MeshD-Flow Flexible Mesh (D-Flow FM) is the new software engine for hydrodynamical simulations on unstructured grids in 1D-2D-3D. Together with the familiar curvilinear meshes from Delft3D 4, the unstructured grid can consist of triangles, pentagons (etc.) and 1D channel networks, all in one single mesh. It combines proven technology from the hydrodynamic engines of Delft3D 4 and SOBEK 2 and adds flexible administration, resulting in:
An overview of the current developments can be found here. The D-Flow FM - team would be delighted if you would participate in discussions on the generation of meshes, the specification of boundary conditions, the running of computations, and all kinds of other relevant topics. Feel free to share your smart questions and/or brilliant solutions!

Hi All,
I have a simulation that runs without any problem in parallel, but gives the error in the title when I run it on a single processor.
These are being run on a Windows 7 x64 machine.
I am attaching my tri-diag file. Does anyone have any idea what could be the matter?

Hi Christopher,
The Windows version of Delft3D-FLOW is 32bit, with a memory limitation around 2Gb. Your model is too big to fit in memory when being run in one process. When running in parallel the domain is devided over several processes, each using less memory than the single process run.
64bit Windows version is on our TO DO list.
Workarounds:
Use the 64bit Linux version
Use the single precision version
Run in parallel
Simplify your model
Regards,
Adri

Thanks Adri, I thought that might be the problem....I'll go to one of the workarounds.
