Credits pricing

Standard Credits
Standard Credits are valid for one year
Great for ad hoc simulations at irregular intervals

Standard credits

Standard credits can be used for any application. Credits deductions are calculated based on per core, per hour and type of applicaton used.

Amount Price Total
100 credits .25c $25
2500 credits .20c $500
5000 credits .15c $750

In order to buy credits or load a voucher, please log in.

How the standard credits work

On payment credits used are calculated in the following way : Per hour x CPU x per variable rate.

The variable rate depends on the application. All applications except for ADF is a variable rate of 1. ADF is a variable rate of 2.

When referring to a CPU we are talking about individal cores on a processor. So a quad core processor would have 4 cores. Hyperthreading is disabled.

An example of how the credits are calculated is listed below.

Appliction CPU Hours Variable Rate Total credits deducted
ADF 12 x 2 x 2 = 48
All others 12 x 2 x 1 = 24

FEKO suite version 7.0 available on CrunchYard

Feko, the comprehensive electromagnetic simulation software, has released their 7th version, and it’s available on CrunchYard. The new version adds a finite difference time domain solver (FDTD) as well as a powerful hybridization of Multilevel Fast Multipole Method and Physical Optics (MLFMM and PO). The release has been eagerly awaited and features three new import file formats (Gerber, ODB++ and 3Di). FEKO 7 is also available via FTP and scripting access on CrunchYard for advanced users.

CrunchYard is pleased to announce direct scripting and FTP access for advanced users.

This new service allows advanced users to interact dynamically with CrunchYard in conjunction with our easy to use web portal. Parameter variations across simulations can be scripted in your own code and submitted to CrunchYard in real time.

In additional, all FTP and scripting activity is mirrored on users personal CrunchYard profile.

FTP and scripting access is free and granted on a request basis. The new service applies to all codes on CrunchYard.

Other licensed codes are available on request.
