Getting Started With CarSim in NI VeriStand

Updated Mar 20, 2024

Environment

Software

  • VeriStand

Operating System

  • LabVIEW Real-Time (NI Linux Real-Time)

CarSim delivers the most accurate, detailed, and efficient methods for simulating the performance of passenger vehicles and light-duty trucks. It is used worldwide by hundreds of OEMs, Tier 1 suppliers, universities, and government research labs. CarSim has a standard interface to NI LabVIEW and VeriStand. This article takes VeriStand 2021 R3 and CarSim 2019.1 as examples to explain how you can use CarSim in NI VeriStand.

Prerequisites

Before reading this article, ensure that you are familiar with CarSim. For more details about CarSim training, please contact Mechanical Simulation.

Create CarSim project

Create an empty folder - CarSim project for example on the PC (The path of the folder can't include any Chinese characters). Open the CarSim, then click Browse for another database... to select the created folder. Ensure that the CarSim Solver for Linux-RT is in the License Settings.

Install RT Solver

If this is your first time using CarSim on your Linux RT target, you should install the RT solvers to the target through Tools >> Install RT Solvers to Target...

After the configuration, click Install. If the following error is triggered, you should create the above path /usr/CarSim/2019.1 on the Linux RT manually.

After the configuration, click Home back to the main page. Then click Build to create a so file for VeriStand. If the configuration is perfect, the following message shows. The vs_nivs.so file is located at the same path of the above VeriStand project file.

Click Send, then Open to open the  VeriStand project - CarSim.nivsproj. You should import the vs_nivs.so file to the Simulation Model if it is the first time you open the VeriStand project. Finally, you can deploy the VeriStand system definition file to run the CarSim.
