When people say "download Simscape," they often mean the base product. However, the full power comes from domain-specific add-ons:
| Product | Purpose | | :--- | :--- | | Simscape (Base) | Fundamental blocks for electrical, mechanical, hydraulic, and thermal domains. | | Simscape Electrical | Semiconductors, motors, power electronics, batteries. | | Simscape Fluids | Gas and liquid systems, valves, pipes, heat exchangers. | | Simscape Multibody | 3D rigid-body mechanics, joints, forces, CAD import. | | Simscape Driveline | Transmission, clutches, differentials, vehicle dynamics. |
Choose the right combination for your project.
| Issue | Probable Cause | Solution |

| "Simscape not found" | Path not updated. | Run rehash toolboxcache in the command window or restart MATLAB. |
| License Error | License does not include Simscape. | Contact your IT administrator to upgrade the license or check the MathWorks Account portal. |
| Offline Installation | No internet on target machine. | Use the "Download without installing" option on the website to create a complete package on a USB drive, then transfer to the offline machine. |
