CPU
The CPU is the most important component for COMSOL Multiphysics, as it determines the speed of solving the equations and updating the graphics. COMSOL Multiphysics supports parallel computing, which means that it can use multiple CPU cores to speed up the calculations. Therefore, the more cores and threads your CPU has, the faster COMSOL Multiphysics will run.
However, not all CPU cores are equal. COMSOL Multiphysics also benefits from a high clock speed, which is the frequency at which the CPU performs operations. A higher clock speed means that each core can process more instructions per second. Therefore, you should look for a CPU that has a good balance between the number of cores and the clock speed.
Another factor to consider is the cache size, which is the memory that stores frequently used data and instructions for faster access by the CPU. A larger cache size can improve the performance of COMSOL Multiphysics by reducing the latency and bandwidth issues. Therefore, you should look for a CPU that has a large cache size.
The minimum comsol pc requirements for the CPU are:
A 64-bit processor with SSE2 instruction set support
A dual-core processor or better
A clock speed of 1 GHz or higher
However, these are only the minimum comsol pc requirements to run COMSOL Multiphysics. To get better results and faster solutions, we recommend that you choose a CPU that has:
A quad-core processor or better
A clock speed of 3 GHz or higher
A cache size of 8 MB or higher
Some examples of CPUs that meet these recommendations are:
Intel Core i7-10700K (8 cores, 16 threads, 3.8 GHz base frequency, 5.1 GHz max turbo frequency, 16 MB cache)
AMD Ryzen 7 5800X (8 cores, 16 threads, 3.8 GHz base frequency, 4.7 GHz max boost frequency, 32 MB cache)
Intel Xeon W-2295 (18 cores, 36 threads, 3 GHz base frequency, 4.6 GHz max turbo frequency, 24.75 MB cache)
AMD Ryzen Threadripper 3960X (24 cores, 48 threads, 3.8 GHz base frequency, 4.5 GHz max boost frequency, 128 MB cache)
RAM
The RAM is another important component for COMSOL Multiphysics, as it stores the data and results of the simulations. The more RAM you have, the larger and more complex problems you can solve with COMSOL Multiphysics. The RAM also affects the performance of parallel computing, as each CPU core needs enough RAM to work efficiently.
The minimum comsol pc requirements for the RAM are:
4 GB of RAM
However, this is only enough to run simple models with small meshes and few degrees of freedom. To run more realistic models with larger meshes and more degrees of freedom, we recommend that you have:
At least 16 GB of RAM
At least 2 GB of RAM per CPU core
ECC (error-correcting code) RAM for reliability and stability
Some examples of RAM modules that meet these recommendations are:
