New version S-T 7.0

New version S-T 7.0 with a new structure

Multi-calculation project files in place of single calculation files
In Simu-Therm 7.0 steady state heat loss calculations belonging to a construction project are collected and processed in multi-calculation a project work file. The calculations in the project file can be managed, printed and modified together or in subsets.

This new structure of Simu-Therm 7.0 brings a lot of additional benefit for frequent users.

Modification of calculations. e.g:

  • Switching of temperatures in the hot and cold face
  • Switching of tube diameter
  •  Search and replace materials.
  •  Search and replace text
  •  Search and replace atmospheres

Additionally ambient cases (e.g. summer/winter) and operation cases (e.g. high/low inside temperature) can be defined and applied to the calculations.

 Existing calculation files (*.ht1 files) still can be opened and included into a project.

Multiple material data files

Material data in up to 10 different files

Whereas up to now Simu-Therm could handle only one material file containing the data of the whole material collection, S-T can access 10 material files at the same time.

If several sources exist (e.g from customers) it is not necessary anymore to create a combined file. Moreover it is very easy to inlude material files temporarily.

New way of printing apart from Excel

Up to now printouts in Simu-Therm were done by transmitting the data to Excel sheets and trigger printing in Excel. In 2006 a new feature was implemented which enables the user to print directly from Simu-Therm.

The direct printing is for customers who have no Excel license or work with Excel under restriced access rights. The print layout can be controlled by commands in a text file.
