“… A very good quality-price ratio; I myself have a complete year package and with that you have a comprehensive software package. I can recommend it to everyone.”

8FAQ

Questions about prices.

8.1How is pay-per-use billed?
Per minute of use, from prepaid credit. An idle hour is never charged. Top-ups start at €350.
8.2Does credit expire?
No. Your credit never expires: unused credit stays on your account.
8.3What happens when my credit runs out?
The programs don’t open models again until you top up or buy a licence. You do both in the program.
8.4What does the €4,000 cap mean?
Pay-per-use never costs more than €4,000 per computer per calendar year, all programs together. The count starts again every 1 January. You’d reach it at 27.8 hours a month of 2D or 22.2 hours of XFEM4U; long before that, a licence is cheaper. The cap is a safety net, not a plan.
8.5When is a licence cheaper than pay-per-use?
Above about 12.3 hours a month. The sums: €1,770 ÷ €12 = 147.5 h a year for Basic 2D, and €2,218 ÷ €15 = 147.9 h for Advanced. The calculator does it for your own mix.
8.6Can colleagues share one balance?
Yes. Everyone on your account can use the same credit at the same time. The cap still counts per computer.
8.7Single-user or network licence?
A single-user licence is for one person, on up to 2 workstations but not on both at the same time. A network licence is priced per person calculating at the same moment, on as many computers as you like.
8.8What does Premium add?
IDEA StatiCa export, Tekla import, DXF export and Python, plus priority support: your questions are answered first. That’s for annual and network licences; pay-per-use includes every feature already, with standard support.
8.9What is XSpreadsheets, and what does it cost?
An Excel workbook of parametric modules that build XFrame2D and XFEM4U models. It counts in the 2D tier. With pay-per-use, the models it builds are billed in the program that runs them.
8.10How do I pay?
Online on this site, inside the program with iDEAL, PayPal or card, or by invoice: e-mail info@struct4u.com. Bought online, a licence or credit is active as soon as the payment is confirmed.
8.11Are the prices with or without VAT?
Without VAT: Struct4U sells to businesses. The switch at the top of the page shows them with Dutch, Spanish or Portuguese VAT. Where VAT is due, it’s calculated when you pay.
8.12Will prices go up?
Once a year, in line with EU inflation. The date of the price list is at the top of this page.
8.13Are new versions and support included?
Yes, in every option. Standard support runs Monday to Friday, 9:00–17:00 CET, and you get an answer within one working day. Premium licences get priority support.
8.14How do I start?
Download the program free and calculate for an hour without registering. When you register in it, you get €100 of credit as a welcome gift: about 8 hours of 2D or 6½ hours of XFEM4U. No card needed.
8.15Is it free for students?
Yes, for a year, with the e-mail address of your university or college. Output carries a watermark, and commercial use isn’t allowed.
