We have a FAQ that has extensive questions that has been ask by customers and answered by our experts.We also have a help desk that will put you in touch with the experts themselves with ticket tracking that will alert you when your issue has a solution and is ready for you.Majority of these issues pertain to PCs adapting incorrectly to HyperChem.
Hyperchem 7 How To Properly InstallThe licensing Section of this page goes through some licensing issues and how to properly install a license to run HyperChem. In addition, the following links go directly to the Support page for your specific product: Windows Mac iPhone, iPod, iPad. The optimization lost some precision when results were sent back to the front end. Uniting 3D visualization and animation with quantum chemical calculations, molecular mechanics, and dynamics, HyperChem puts more molecular modeling tools at your fingertips than any other Windows program. Its drawing and rendering capabilities and ease of use are standards for the industry. HyperChem 8 has been prepared to provide reliable computation in this new environment. In some cases, however, manufacturers graphics drivers (OpenGL drivers) have not proved to yet be up to the earlier standards of Windows XP. Where problems have been seen, installation of a new driver from the graphics card manufacturer has often eliminated any problem. To use HyperChem effectively, one should have a good graphics card and a compatible newer driver. However, inexpensive machines will often have graphics hardware, included on the motherboard, that results in relatively slow manipulation of large molecules, compared to that with a modern 3rd-party graphics card. These packages may include other ab initio and semi-empirical packages such as GAMESS and MOPAC2007. Included with HyperChem 8 is the copyrighted source code for a number of these interfaces. A standard menu item in HyperChem, Third-Party Interfaces executes a standard HyperChem Command Language (HCL) script installed with the product. This script has the pre-defined name, thirdparty.scr. This script can be modified by users to add other third-party applications but comes included with a variety of evolving interfaces. These interfaces uses the elegant open architecture features of HyperChem that allow software outside HyperChem to interact and readwrite information tofrom HyperChem. The interface software is copyrighted Open Source software that any HyperChem user can modify to improve the interface or to create a new interface to hisher own software. The interfaces generally allow a user, for example, to run a GAMESS job from within HyperChem, and get back the results for display. The first level of interface, that is included to begin with in HyperChem 8, allows a user to display optimized structures, vibrational spectra and animations of normal modes plus 3D renderings of orbitals, electron densities, and electrostatic potentials. It is to be expected that these interfaces evolve to become richer as users and members of Hypercube, Inc. This has been the case even when the back end resided on another machine on the network. ![]() In Batch mode the computation is severed and carries on by itself while HyperChem is free to read in a new molecule or continue on in any way it pleases, including spawning more batched jobs. The back ends have been instructed by the front end that they are indeed batch processes and instead of sending their results live to the front end, they create a.ext file that can be read at any later time into the HyperChem front end to display the results just as if the calculation was run interactively. Thus, until now coordinates of molecules at the front end (i.e. HyperChem) were single precision while coordinates at the back end (e.g. HyperGauss) were double precision where they needed to be. This saved time for graphical and communication operations where precision was not critical. However, small discrepancies between the front end and back end coordinates were occasionally noticeable such as when restarting an optimization.
