Computational Physiology,  Simplified.


Meet the  Online Muscle Simulator (OMS)

It's the next generation of muscle physiology research. It's in the cloud—so it's powerful, fast, and always ready to deploy. Even better, it works without having to write a single line of code. Accumulus Bio's OMS  is optimized to run with speed, elegance, and simplicity, so you can focus on experimentations and discovery. It's computational muscle physiology designed for the 21st-century global researcher.


Muscle Physiology. Now in the Cloud.

Running computational muscle physiology models is difficult—that's why we built OMS. With OMS, there's no need to manage expensive, complex infrastructure, configure servers to deploy models, or mantain data storage platforms. You can deploy computational physiology models with the click of a button and the models will run on our server fleet and manage the data on our cloud platform. After running models,  you can easily visualize and analyze results using built-in tools, all within your browser. All over the world, OMS is empowering muscle and heart researchers to go from experimental data to insights in minutes.

Get Started with OMS in 
3 Steps

Step 1: Load Experimental Parameters

To get started, load parameters from experiments into the OMS, including decoupling, phosphorylation, and calcium ion parameters. OMS supports a broad library of model parameters for researchers to access. To give researchers greater flexibility, OMS comes with built-in model parameters from peer-reviewed scientific papers, allowing researchers to use the OMS without needing experimental values for every model parameter.

Step 2: Compute Model

Next, deploy the model loaded with experimental data onto our scalable fleet of servers with the click of a button. No need to manage complex server infrastrucutre or coordinate data managment. A completely managed solution, the OMS' powerful backend abstracts all complexity in model deployment, allowing you to focus completely on experimentation and interpreting model findings.

Step 3: Visualize and Analyze

After running the model on our servers, the OMS packages simulation output and beautifully visualizes the data. Using built-in tools, you can compare experimental data with simulations, to explore potential mechanics underlying experimental results.  The OMS' analytic tools can be used to compare previous model runs with each other, allowing you to explore the impact of different parameters on muscle function to provide broader context for experimental findings.
