In 1995, there was a breakthrough in the numerical simulation of magnetohydrodynamic (MHD) flow by Glatzmaiers and Roberts, called GR95 (Glatzmaiers & Roberts, 1995b). From 1950 to 1990, the dynamo theory has shown that the principle of a homogeneous dynamo process is possible and has elucidated the parameter prerequisites and model constraints. As emerging from numerical simulations, details of these mechanisms achieve a self-sustaining magnetic field (Aubert, 2020 Buffett, 2000 Yadav et al., 2015). Earth's magnetic field is generated and maintained by a strongly coupled mechanism known as geodynamo (Roberts, 2007). Paleomagnetic records indicate that the Earth's geomagnetic field has existed for at least 3 billion years, with a roughly reversal rate of hundreds of thousands of years. Still, appropriate assumptions can be made to take this variation into account. Comparing with other scaling laws previous wisdom holds, we propose that the effect of viscosity diffusion is non-negligible for both existing weak and strong dynamo regimes. In a quasi-MAC regime, the Lorentz force instead of the inertial force enters into the first-order agostrophic force balance, though the viscous force still plays a role. Furthermore, we conducted a local force balance analysis and demonstrated that the balance shifts under different. The reason that increases with is essential that increasing breaks the Taylor-Proudman constraint and drops the critical Rayleigh number, but this kind of increase of does not give a stronger. The magnetic field does not change much with when the driving force is not too strong ( ) but decreases with by a scaling law of when geodynamo operates in a very vigorous mode ( ). While in the strong field mode, varies very slowly by a scaling law of. In the weak field mode, the fluid velocity varies with by a scaling law of. To boost these, taking the outer core viscosity, we studied its impacts on weak and strong field geodynamo outputs by varying in two orders of magnitudes. Existing scaling laws need to be tested by numerical simulations. In case you constantly need to connect to your work computer from remote locations, this is a proper utility.Exploring geodynamo's scaling laws is of great importance when a tremendous gap still lies between realistic physics and estimated model parameters. Most of your attention is required when setting up connection, with the rest being handled by the application. To end withĪll in all, Viscosity can come in handy to a large variety of business and individuals, by creating a suitable means of data transfer, without exposing it to hacks and attacks. By default, the application requires you to manually connect to a created service, but this can be solved by an option that automates the task.

You are free to organize more entries in folder for a better view. Create and monitor multiple connectionsĪs mentioned above, the application does not limit you to a single connection.
However, you must specify a default gateway, DNS details, with the possibility to include shaper, fragment, tun MTU and inactive. What's more, your data can be kept safe by tunneling all data through a VPN connection.

Several SSL / TLS clients can be used for authentication, and for enhanced security you can opt for a username and password check. The application lets you set authentication, networking or proxy options. This is where it gets tricky, with various requirement fields asking for technical info. If neither of the import methods provide aid, you might need to set up a connection manually.
The same applies for a server, with the possibility to import connection data once your credentials are provided. However, if you already have a configuration file saved on your computer it can be used as such. This is easily done from the preferences window and you are not limited to a single one. Import configurations from a file or serverįirst off, you need to set up at least one connection before being on the safe side. Applications such as Viscosity offer a helping hand in this regard, allowing you to create a secure tunnel through which to safely access every part of the internet. Nowadays, with businesses being dependent of the web, you need to make sure that no one can trace your actions, to decrease the risk of being the victim of a virtual attack.
