Donation Sponsor

$5 $10 $25 $100 $200 Other

If you are not sure or not able to commit to a regular donation, but still want to help the project, you can do a one-time donation, of any amount.

Choose freely the amount you wish to donate one time only.

We call sponsoring the act of donating money recurrently to the FreeCAD project. You can do that as an individual or as a company or institution, through different channels or platforms, depending on your preferences.

Sponsoring FreeCAD allows its developers to count on a steady flow of income, so it allows the FPA to plan things ahead, and the FreeCAD developers to invest themselves more seriously into FreeCAD.

To encourage persons and companies to sponsor the FreeCAD project, we have created different sponsoring tiers. When donating regularly to the project, unless you prefer to stay anonymous, your name, company name and/or logo will be featured on this website, depending on the tier you fit into:

♥ Normal sponsor : from 1 USD / 1 EUR per month. You will not have your name displayed here, but you will have helped the project a lot anyway. Together, normal sponsors maintain the project on its feet as much as the bigger sponsors.
🥉 Bronze sponsor : from 25 USD / 25 EUR per month. Your name or company name is displayed on this page.
🥈 Silver sponsor : from 100 USD / 100 EUR per month. Your name or company name is displayed on this page, with a link to your website, and a one-line description text.
🥇 Gold sponsor : from 200 USD / 200 EUR per month. Your name or company name and logo displayed on this page, with a link to your website and a custom description text. Companies that have helped FreeCAD early on also appear under Gold sponsors.

Instead of donating each month, you might find it more comfortable to make a one-time donation that, when divided by twelve, would give you right to enter a sponsoring tier. Don't hesitate to do so!

Choose freely the amount you wish to donate each month.

Please inform your forum name or twitter handle as a notein your transfer, or reach to us, so we can give you proper credits!

FEM SolverZ88

Description

The SolverZ88 command enables usage of the Z88 solver. It may be used for:

Setting analysis parameters
Selecting working directory
Running the Z88 solver

Installation

To use the Z88 solver, the OpenSource version of Z88 (Z88OS) needs to be installed:

Download the ZIP file from the Z88OS website.
Extract the ZIP to a folder of your choice.
In the FEM preferences go to the Z88 tab and there set the path to the z88r binary. If you are on Windows this would be the path to the file z88r.exe that is in the subfolder ~\bin\win64 of the folder where your extracted the ZIP.

Usage

After the creation of an Analysis container, use one of the following alternatives:
- Select Solve → Solver Z88 from the menu.
- Press the S then Z shortcut keys.
Double click the SolverZ88 object.
Select the Analysis type.
Click the Write button.
Click the Run button.

As a result you get an object called Z88_xxx_results (depending on the run simulation) in the Tree view. This is the same kind of result object one gets when running the CalculiX solver. Starting from this, you can visualize the results using Post Pipeline and Clip Filters.

Preferences

See the Z88 preferences for the possible solver settings like the used solver method.
