Ever needed to run engineering calculations but got stuck setting up Python? Or wanted to iterate on analysis without losing track of changes?
In this tutorial, we'll create and modify a Bode plot for an RC filter, showing how Dystr makes complex calculations simple and trackable.
Creating Your First Calculation
Click the "+ New Compute" button
In the input box at the bottom, describe what you want to calculate and hit Enter:
Create a bode plot for a passive low pass RC filter. R = 700, C = 1uF. Print the -3dB frequency for the filter (in Hz) above the plot. Also, draw a vertical red dashed line at the -3dB frequency
Click "Run Compute"
Dystr automatically:
Wrote the necessary Python code
Started a new compute environment in your Workspace
Created the Bode plot
Calculated and displayed the cutoff frequency
Added the vertical marker
Iterating on Your Analysis
Want to compare different resistor values? Simply describe the change:
Lets overlay a comparison between 700 and 900 ohms
The code updates automatically to show both filter responses. You can continue refining by:
Adjusting parameters
Adding new comparisons
Modifying the visualization
Fine-Tuning Parameters
Need to try a different value?
Click into the code
Change parameters directly (e.g., R from 900 Ω to 1200 Ω)
Click "Save + Run Compute"
Tracking Changes
Every run is automatically tracked in the Activity Log. Your team can:
See when calculations were run
Review parameter changes
Compare results over time
No version control needed!
Understanding the Math
Click "Math View" to see:
Clear explanations of the calculations
Mathematical equations in standard notation
Step-by-step breakdown of the analysis
This helps team members understand the computation regardless of their coding experience.
