Windows 11 version, compilation in December 2023

UPDATE HISTORY

The Future

In 2023, I purchased new code signing certificates and associated software so that virus checking software might be appeased and allow installation of Igpet. I can't guarantee that because code signing and notarization are just black boxes to me. My ignorance, the difficulty of implementation and the high cost is driving me out of business. If I remain healthy, I plan to make a 2025 version, a 40th anniversary version and most likely the last. At that point updates will stop but distributed instal packages will still be valid because they have time stamps. Keep you DGMs (Mac) and ZIPs (Windows)!

December 2023

Continuing revision to installation packaging, with new signing certificates and notarization process for Mac. Improvements to symbol customization. New sym.txt files can line with and scale factors so that each symbol can be given different sizes.

Igpet: a modeling and graphics package for Igneous Petrology

I began creating software for igneous petrology around 1972, while in graduate school. Once personal computers arrived, the software got complicated enough that I needed motivation to justify the time required for maintenance so, in 1985, I made a business, Terra Softa. I maintain three programs and provide them in a package called Igpet. Igpet is the core program, but there is also a Mixing program that calculates fractional crystallization and magma mixing using least squares, and a CIPW program. I consider the CIPW program freeware. 

Examine the Igpet Gallery of images posted below. Click the down-pointing arrow on the right side. The image gallery is the quickest introduction to Igpet's capabilities. Some Word versions may lower the image quality so check the pdf files below for an accurate view of the current PDF graphics output. The Windows graphics prior to 2020 were WMF files.

For a better idea of what is in Igpet, download the Igpet Paper (2017), the Igpet Manual and the Workbook below. Click the down-pointing arrows on the right side. IgpetEvolution is a draft that has mostly been superseeded.
