Frequently Asked Questions (FAQ)
Q1: What is the difference between cloud-based and desktop simulation software?
Cloud-based simulation software, like SimScale or Onshape, runs in your web browser on remote servers. This means you don’t need a powerful local workstation, you can access it from anywhere, and collaboration is often easier. Desktop software, like SOLIDWORKS Simulation or Ansys Discovery, is installed on your local computer and uses your machine’s resources (CPU, GPU, RAM) to perform calculations.
Q2: Are free simulation tools powerful enough for professional work?
Yes, but with a major caveat. A tool like OpenFOAM is exceptionally powerful and is used by leading companies and research institutions. However, its “cost” is not in licensing fees but in the significant time and expertise required to learn and use it effectively. For professional work, you also lack the dedicated technical support that comes with a commercial product.
Q3: How much should I expect to budget for simulation software as a small business?
The range is vast. You can start for free with OpenFOAM or a startup license for Fusion 360. A professional subscription for an all-in-one tool like Fusion 360 can be under $1,000 per user per year. More specialized or high-end tools like Ansys Discovery or SOLIDWORKS Simulation packages can range from $4,000 to over $15,000 per user per year
