Using Restart Files Demo

Introduction

This tutorial explains how to use restart files in ResFrac, a powerful software for simulating hydraulic fracturing and reservoir behavior. Restart files are essential for resuming simulations without starting from scratch, saving time and computational resources. This guide will walk you through the process step-by-step, ensuring you can effectively manage your simulations.

Step 1: Understanding Restart Files

• What are Restart Files?

  • Restart files save the current state of your simulation.
  • They allow you to pause and resume simulations without losing progress.

• Why Use Restart Files?

  • To save time and resources by not restarting simulations from the beginning.
  • Useful for long-running simulations where interruptions may occur.

Step 2: Creating a Restart File

• Setting Up Your Simulation:

  • Start your simulation as usual in ResFrac.
  • Ensure all input parameters are correctly configured.

• Generating the Restart File:

  • Navigate to the simulation settings.
  • Locate the option to enable the creation of restart files.
  • Save your simulation after initial run, which will automatically generate the restart file.

Step 3: Resuming a Simulation with a Restart File

• Loading the Restart File:

  • Open ResFrac and select the option to load a simulation.
  • Find the folder where your restart files are stored.
  • Select the relevant restart file to load your previous simulation state.

• Checking Simulation Parameters:

  • Verify that all parameters and settings are intact from your previous session.
  • Make any necessary adjustments before resuming the simulation.

Step 4: Running the Simulation

• Starting the Simulation:

  • Once everything is set, initiate the simulation.
  • Monitor the progress to ensure it resumes as expected.

• Common Pitfalls:

  • Ensure the restart file is from a compatible version of ResFrac.
  • Double-check that no critical parameters have changed since the last run.

Conclusion

Using restart files in ResFrac can significantly enhance your workflow by allowing you to pause and resume simulations seamlessly. Remember to generate restart files regularly and ensure you load the correct version for your simulations. For further learning, consider exploring additional features of ResFrac that can optimize your simulation processes.
