|Start, Stop, Pause, Continue||see the corresponding buttons below|
|Prints the 3D graph. Works only in the Pause mode (if it works!).|
|Arrange windows||Arranges the output-windows (on some browsers!).|
|Bring windows to top||Sets the output-windows in front of the main window.|
|Show in frame||Shows the simulation in an resizable window.|
|Start||Opens a dialog to set the start-parameters. "Ok" starts the simulation.|
|Stop||Resets the program completely: all output is lost! The output-windows are closed.|
|Pause||Pauses the simulation (e.g. to print results)|
|Continue||Resumes a paused simulation.|
|Settings||Opens the window "Settings" (which contains a pop-up menu to open the other output-windows9.|
You can turn the simulation-cube around the x and y axes by dragging it with the mouse. (On some browsers also the arrow-keys might work).
The atoms are shown in different size and colors depending on their z-position. The minimal size is 5 pixels.
|Algorithm for the integration of Newtons's equations|
|Priority||1 bis 9||Priority for the applet. Use a lower priority if the response of the system is slow.|
|Preset atomic values for a few cases.|
|Atoms||> 1||Number of atoms.|
|Start distribution of the atoms. The face- and the body-centered lattice are not yet implemented.|
|Comment||string||Comment for the present simulation.|
|Output file||string||Name of the output-file (if supported on your system).|
|Interval||> 0; 0 no output||Output interval to file in steps.|
|Start values||Pop-up menu to select certain phase points dependent on the atom|
|Temperature||> 0||Temperature in Kelvin.|
|Density||> 0||Density in mol/m3|
|Time step||.10-14||Time step in s.|
|Cutoff radius||> 2.5||Cutoff radius in sigma units.|
Customized Atom Parameters:
|Name||String||Name of atom.|
|Mass||> 0||Atomic mass in atomic mass units (amu)|
|Epsilon||>= 0||Potential depth in J.|
|Sigma||>= 0||Collisional distance in m.|
|Atom||Using "Edit" or the entry "Customized" the atomic parameters may be changed.|
|Comment, Output file, Interval||For saving data in a file on disk. The browser might ask you for lower security to save the data (does not work on all systems).
Some thousand simulation steps might need several Mbytes!
|Benchmark||Starts a 5s benchmark-calculation for the parameters chosen. As a result you get the number of steps per second performed on your computer under the given conditions.|
|Update frequency||Update frequency of the output-windows.|
|Set temperature||Resets the temperature to the value in the input-field. The user should reset the temperature repeatedly until equilibrium is reached. The values in the accumulator-window are also reset.|
|Window||To select and show one of the other output-windows.|
Shows the start-parameters. "Show" gives the atomic data.
Shows the results of the present step. The pop-up menu at the bottom together with the button "Show" graphs in a new window the selected property versus time.
The last 100 steps are drawn on the right side of the red bar, while all the previous steps are shown in a compressed form on the left side. Pressing the right mouse button or THE mouse button while holding down the "Shift"-key restarts the graph.
Shows the accumulator values divided by the number of steps, i.e. the average values (since the last reset). "Reset accumulator" resets the accumulators to 0. The pop-up menu at the bottom together with the button "Show" graphs in a new window a histogram of the one- or three-dimensional velocity distribution.
