# Reassigning hypotheses and algorithms

After you have created a mesh or submesh with definite applied hypotheses and algorithms you can edit your mesh by assigning new hypotheses and algorithms or unassigning the applied hypotheses and algorithms.

To assign or unassign algorithms and hypotheses:

1. In the Mesh menu select the Edit Hypothesis, the following dialog box will appear:

This dialog box contains the following fields:

- Mesh or SubMesh field: here you should enter the name of the mesh or submesh for which you would like to assign or unassign hypotheses and algorithms. It can be also done by choosing the required mesh or submesh in the Object Browser or in the 3D viewer;

- Hypotheses set of fields containing two columns:

- Available: the hypotheses which have been created in the current study;

- Used: the hypotheses which have been applied to previously selected mesh or submesh.

- Algorithms set of fields containing two columns:

- Available: the algorithms which have been created in the current study.

- Used: the algorithms which have been applied to previously selected mesh or submesh.

2. Double-click on the definite algorithm or hypothesis to move it from the Available column into the Used column and vice versa. Thus you will be able to apply new hypotheses and algorithms to your mesh or unassign the applied hypotheses and algorithms.

3. Confirm your changes by clicking the OK button.

After modification of applied algorithms you should recompute your mesh once again.

You can also unassign an applied algorithm or hypothesis by right-clicking on it in the Object Browser and choosing from the associated popup menu the Unassign Algorithm or Unassign Hypothesis item.
